Banerjee and colleagues at Harvard and Rice Universities author feature story, “Two-Dimensional van der Waals Materials,” published in the September 2016 issue of Physics Today

The article provides an overview of the physics, technology, and device applications of 2D materials including graphene and beyond-graphene 2D materials as well as their wide variety of heterostructures forming completely new materials known as “van der Waals solids”. The visionary article also discusses the prospects of employing such 2D materials for realizing layered nano- structures devices and circuits with atomic precision- a scientific dream of renowned physicist, Richard Feynman.

Professor Banerjee’s group have made seminal contributions toward advancing the understanding of 2D materials physics and uniquely exploited their properties in overcoming the limitations of conventional bulk materials (such as silicon and III-V semiconductors) for addressing power dissipation and other fundamental challenges in nanoscale transistors, interconnects and sensors. For example, a key device application highlighted in the article is a new class of transistors, the 3D/2D vertical heterostructure tunnel-field-effect-transistor demonstrated by Professor Banerjee’s group (Nature, 2015) that exhibits unprecedented low leakage currents and can switch with only 0.1 volts resulting in over 90% savings in power consumption.

Physics Today is the most influential and closely-followed physics magazine in the world, and more than 120,000 subscribers across the fields of STEM receive the publication every month. It is also the flagship publication of the American Institute of Physics that informs readers about science and its place in the world with authoritative features, news stories, analysis, and fresh perspectives on technological advances and ground-breaking research.

Pedro was born in California and moved at a young age to Peru. His entire family is Peruvian, but he will be the third generation to earn a Ph.D. from a UC school (his grandfather ​went to UC Riverside and his father ​went to UC Davis). Pedro studied Electrical Engineering at the Pontifical Catholic University of Peru and will be pursuing a Ph.D. at UCSB in Electrical Engineering, with an emphasis on Communications, Control, and Signal Processing. Pedro explained, “Since school, I have had an equal love for math, letters, and arts. I thought of engineering as a possible way to combine those three.” He is interested in the field of Control Theory, which deals with a considerable amount of math and has a lot of theoretical work, as well as its application to biology, sociology, complex systems, and other applied math studies.

Pedro said that he is looking forward to making Santa Barbara his second home, and he is excited about both the academic opportunities and the fun activities it has to offer. Something you might not know about Pedro is that he has ​created over 27 paintings and has done four public art expositions in Peru. He also plays frontón, a Peruvian sport similar to squash, and he has a basic understanding of Quechua, an indigenous Peruvian language.

At UCSB, there are a variety of gender identities represented in our student population. From the current demographic data we have collected on the incoming graduate student class, 52 percent of students identified as men and 48 percent identified as women. Starting with the Fall 2017 admissions cycle, all applicants to UCSB will have the option to choose among six gender identities listed on admissions forms: male, female, trans male, trans female, gender queer/gender non-conforming, and different identity. Additionally, all current UC students will be able to update their gender and sexual identity through the UCSB Registrar if they would like to.

Most of the incoming graduate students are between the ages of 22 and 30, but our youngest incoming student is 20 years old and our oldest is 57 years old. Sixteen percent are first-generation college students, and 25 percent of our new grad students identify as an underrepresented minority.

UCSB’s graduate students are coming from 45 different countries – from China to ​Chile, ​Sweden to South Africa, Mexico to Malaysia – representing nearly every continent. In fact, roughly one-third of incoming students (247, to be exact) are coming from places outside the country. Our U.S. students hail from 43 of the 50 states, but over half of them are California natives.

The most popular disciplines that our new graduate students chose were Environmental Science and Management (99 new students), the Teacher Education Program (81 new students), and Electrical and Computer Engineering (66 new students). By division, the most new graduate students are in Engineering (​207) and Mathematical, Life, and Physical Sciences (184), followed by Education (​114) and Humanities and Fine Arts (101).

Vivek moved around quite a bit growing up due to his father’s profession, but he spent most of his childhood in Hyderabad, India. “A new city, a new place every 2-3 years – it helped me adapt quickly and expand my comfort zone,” ​he said. “That’s one thing I’ll be carrying with me to Santa Barbara.” Vivek holds a Bachelor of Technology degree in Electrical Engineering from the University of Pune, and he’ll be joining the Electrical and Computer Engineering department at UCSB to specialize in communications and signal processing. ​He explained his research interests by saying, “Today, even though we’re using the Internet at unimaginable speeds, about 60% of the world still lacks basic connectivity, specifically developing nations. Technology in itself is futile if it doesn’t reach the masses. This is what sparked my interest in communications. I envision a future where each and every household ​has standard connectivity.”

Vivek said he is looking forward to ​UCSB’s amazing research facilities as well as the lovely beaches in Santa Barbara. He enjoys exploring new places, playing the guitar, and reading, and he also ​fancies himself a foodie. ​”I’d like to think of myself as a good cook. Well, sort of…! I tend to experiment with new elements. I try out various fusions between different cuisines.”

ECE Professor Pradeep Sen’s work on High dynamic range (HDR) imaging published in IEEE Signal Processing Magazine

September 7th, 2016

cover of Signal Processing magazine
HDR imaging enables the capture of an extremely wide range of the illumination present in a scene and so produces images that more closely resemble what we see with our own eyes

In the article, “Practical High Dynamic Range Imaging of Everyday Scenes: Photographing the world as we see it with our own eyes,” authors Sen (UCSB) and Cecilia Aguerrebere (Duke) explain the problem of limited dynamic range in the standard imaging pipeline and then present a survey of state-of-the-art research in HDR imaging, including the technology’s history, specialized cameras that capture HDR images directly, and algorithms for capturing HDR images using sequential stacks of differently exposed images. Because this last is among the most common methods for capturing HDR images using conventional digital cameras, they also discuss algorithms to address artifacts that occur when using with this method for dynamic scenes.

Finally, they consider systems for the capture of HDR video and conclude by reviewing open problems and challenges in HDR imaging.

V Rosborough in the lab

Rosborough, a Ph.D. researcher in Associate Professor Jonathan Klamkin’s Integrated Photonics Laboratory (iPL), talks about her experience choosing the photonics life

Rosborough was interviewed by The Huffington Post blogger Diane Propsner as a part of her series on “amazing women’s college STEM alumnae.” Rosborough, a Ph.D. researcher in the lab of ECE Associate Professor Jonathan Klamkin, talks about her experience as an engineer who started college early in an academically accelerated program – from getting involved in undergraduate research to what it’s like to be a photonics engineer today.

HuffPo: How did you become interested in integrated photonics?

Rosborough: After graduating [from Mary Baldwin College], I found a master’s program in semiconductor devices at the University of Oregon. As a part of this degree, I completed a year-long internship at IBM, where I had the opportunity to interact with Ph.D.’s in several areas of IC production expertise. When I applied to Ph.D. programs that year, I sent applications to electrical engineering and materials science departments. It was during this application process that I learned about integrated photonics. Photonics excites me because it’s on the cutting edge of research while combining physics and technology. Along the way, although I wasn’t always quite sure where I’d end up, I kept pursuing the types of opportunities that excited me until I found my niche.
