UC Santa Barbara researchers demonstrate seamless designing of an atomically-thin circuit with transistors and interconnects etched on a monolayer of graphene
Researchers in electrical and computer engineering at UC Santa Barbara have introduced and modeled an integrated circuit design scheme in which transistors and interconnects are monolithically patterned seamlessly on a sheet of graphene, a 2-dimensional plane of carbon atoms. The demonstration offers possibilities for ultra energy-efficient, flexible, and transparent electronics.
Bulk materials commonly used to make CMOS transitors and interconnects pose fundamental challenges in continuous shrinking of their feature-sizes and suffer from increasing “contact resistance” between them, both of which lead to degrading performance and rising energy consumption. Graphene-based transistors and interconnects are a promising nanoscale technology that could potentially address issues of traditional silicon-based transistors and metal interconnects.
“In addition to its atomically thin and pristine surfaces, graphene has a tunable band gap, which can be adjusted by lithographic sketching of patterns – narrow graphene ribbons can be made semiconducting while wider ribbons are metallic. Hence, contiguous graphene ribbons can be envisioned from the same starting material to design both active and passive devices in a seamless fashion and lower interface/contact resistances,” explained Kaustav Banerjee, professor of electrical and computer engineering and director of the Nanoelectronics Research Lab at UCSB. Banerjee’s research team also includes UCSB researchers Jiahao Kang, Deblina Sarkar and Yasin Khatami. Their work was recently published in the journal Applied Physics Letters.
By determining simple guidelines, researchers at UC Santa Barbara’s Solid State Lighting & Energy Center (SSLEC) have made it possible to optimize phosphors –– a key component in white LED lighting –– allowing for brighter, more efficient lights.
“These guidelines should permit the discovery of new and improved phosphors in a rational rather than trial-and-error manner,” said Ram Seshadri, a professor in the university’s Department of Materials as well as in its Department of Chemistry and Biochemistry, of the breakthrough contribution to solid-state lighting research. The results of this research, performed jointly with materials and electrical and computer engineering professor Steven DenBaars and postdoctoral associate researcher Jakoah Brgoch, appear in The Journal of Physical Chemistry.
LED (light-emitting diode) lighting has been a major topic of research due to the many benefits it offers over traditional incandescent or fluorescent lighting. LEDs use less energy, emit less heat, last longer and are less hazardous to the environment than traditional lighting. Already utilized in devices such as street lighting and televisions, LED technology is becoming more popular as it becomes more versatile and brighter.
The ARPA-E project selections are for strategies for wide-bandgap, inexpensive transistors for controlling high efficiency systems (Switches) (SBIR/STTR).
The project “Current Aperture Vertical Electron Transistor Device Architectures for Efficient Power Switching” will receive $3,172,205 to develop new vertical gallium nitride (GaN) semiconductor technologies.
The University of California, Santa Barbara Mishra group will develop these technologies to enhance the performance and reduce the cost of high-power electronics. The team’s current aperture vertical electron transistor devices could reduce power losses and reach beyond the performance of lateral GaN devices when switching and converting power. If successful, UCSB’s devices will enable high-power conversion at low cost in motor drives, electric vehicles, and power grid applications.

These awards were announced during the opening ceremony of the event on Sept 10, 2013.
The collaborative effort between the Nanoelectronics Research Lab and Intel’s Mobile Communication (IMC) Group in Munich, Germany, led by Prof. Banerjee is chronicled in the article titled, “ESD Characterization of Atomically-Thin Graphene”. The article provides pioneering demonstration of Graphene’s outstanding resilience under ESD and was selected for the Best Paper Award among over 50 papers chosen for oral presentation by the symposium’s technical program committee for the 2012 September meeting held in Tuscon, AZ. The article was co-authored by Dr. Christian Russ, David Johnsson and Dr. Harald Gossner of IMC.
ESD is a major reliability issue in the electronics industry, being the single largest cause of all integrated circuit failures. At an estimated annual loss of millions of dollars, ESD affects electronics industry production, manufacturing costs, product quality and reliability, and profitability, according to the ESD Association.
Graphene is considered a promising material in a number of areas including electronic devices, interconnects and sensors. Due to its high mechanical strength, transparency and conductivity, it is also attractive for a variety of flexible and transparent electrode applications including touch screens that are critical components of nearly every modern mobile communication gadget. Hence, their resilience against ESD is deemed a key criterion for their wide scale deployment in the near future. This demonstration also opens up many possibilities of employing graphene for ESD protection of future nanoelectronic circuits and systems as well as advanced IC packaging.

In the mid-nineties, UCSB electrical and computer engineering professor Bob York and his team of researchers began working on solving a technology problem for the telecomm industry: how to amplify high frequency signals for use in high-power telecomm.
Traditional techniques used wires on a circuit board to split one signal into many signals, amplify each of those, and then combine them to produce a single amplified signal. In 1996, Professor York and his grad student, Angelose Alexander, developed an entirely new approach. Instead of using wires to split a signal, they broadcasted the signal inside a device and used numerous antennae to receive the signal then amplify it. In doing so, they eliminated the inefficiencies that had plagued the old method and made efficient, high-frequency telecomm possible.
In 2004 Wavestream, a communications company based on technology developed at CalTech, began licensing the technology from UCSB for use in their high power solid state amplifiers. Seeing the value in UCSB’s technology, and being familiar with the process of licensing technology from universities, they began producing amplifiers using both technology developed at UCSB (“deck” amplifiers) and technology developed at CalTech (“grid” amplifiers).
The last nine years have seen Wavestream grow from a small university startup to a thriving company with a global impact, and UCSB has played a major part in that growth. The technology developed at UCSB by Professor York is currently used in 90% of the amplifiers Wavestream manufactures.
The UCSB Office of Technology & Industry Alliances (TIA) was established with two primary responsibilities: to manage the intellectual property developed through UCSB research (including out-licensing) and to manage the many agreements with industry partners that support research collaborations (including research agreements, material transfer agreements, non-disclosure agreements and memorandums of understanding).
