Virginia Nano-Computing Research Group

At the Virginia Nano-Computing Research Group, the focus is on understanding non-equilibrium properties of nano-scale material structures. Our work applies a combined understanding of fundamental physics , chemistry, material science, and device engineering to explore novel device concepts.The research group also explores and utilizse high performance computational resources including the use numerical algorithms to advance the understanding of nanoscale science and engineering. To address the challenges of extending today’s electronic devices to the next generation of devices, science can no longer work out of context to engineering, but rather both should work in tandem. The interdisciplinary nature of our approach is necessary to explain the science and push the engineering of future devices.

Kevin Skadron is Professor and Chair of Computer Science, as well as a Harry Douglas Forsyth Professor and Director and co-founder of the Center for Automata Computing, at the University of Virginia, where he has been on the faculty since 1999. He received his Ph.D. in Computer Science from Princeton University, and his BS and BA degrees in Computer Engineering and Economics from Rice University. He is a Fellow of the IEEE and the ACM, and a recipient of the ACM SIGARCH Maurice Wilkes Award. Skadron’s research interests focus on design and application of accelerators and heterogeneous architectures, including solutions to power, thermal, reliability, and programming challenges. To support research in these areas, he and Mircea Stan have developed the HotSpot, VoltSpot, and ArchFP modeling tools.

HotSpot 6.0 Temperature Modeling Tool

HotSpot is an accurate and fast thermal model suitable for use in architectural studies. It is based on an equivalent circuit of thermal resistances and capacitances that correspond to microarchitecture blocks and essential aspects of the thermal package. The model has been validated using finite element simulation. HotSpot has a simple set of interfaces and hence can be integrated with most power-performance simulators like Wattch. The chief advantage of HotSpot is that it is compatible with the kinds of power/performance models used in the computer-architecture community, requiring no detailed design or synthesis description. HotSpot makes it possible to study thermal evolution over long periods of real, full-length applications.

Professor Poon’s research program is in materials physics. He designs and synthesizes novel amorphous metals, nanostructured materials, and intermetallic compounds. The problems he investigates include structure-property relationships particularly on how atomic- and nano-scale structures determine magnetic anisotropy, thermoelectric performance, and mechanical behavior. His multi-level study employs both  experimental and computational methodologies, utilizing various state-of-the-art electrical, thermoelectric, magnetic, and mechanical probes to measure properties.

The materials studied have the potential for technological applications. In recent years, the effort has resulted  in the discovery of a new type of amorphous metals that exhibit ultrahigh strengths and corrosion resistance. His group has also observed unusual electronic and magnetic structures in the metal-based compounds including resonant state near the Fermi level and half-metallic behavior.

Poon’s work has been recognized by Physics World: 

Nanoparticles Boost Thermoelectric Efficiency

Researchers in the US have unveiled a new high-temperature material that is 60% better at converting heat to electricity than comparable “thermoelectrics”. The material, which is a nanocomposite, is stable up to temperatures as high as 700 °C. It could therefore potentially be used to boost the fuel efficiency of cars by recovering energy from the vehicle’s exhaust heat.

He then came to the US for a PhD in Theoretical condensed matter physics at the University of Delaware. Following a postdoc at Washington University in Saint Louis, he had been assistant and then associate professor at the Institute for Materials Research of the Tohoku University, where the main theme of his research was materials properties modeling from first-principles. This was followed by a 4 years stay at the Sharif University, a visiting associate professorship at UC Santa Cruz, until he moved to the Mechanical Engineering Department of MIT as a research Scientist to work on modeling thermoelectricity, heat transport and related phenomena from first-principles. He is presently pursuing his research interests in the fields of cooling, energy conversion and storage, near-field radiation, and basically in heat management. Keivan Esfarjani’s website
