March 2017

Congratulations to Vivian Wang (BS '17) on her well-deserved award!

As an undergraduate, Vivian has been involved in numerous events on campus. She is a former co-director, and teacher, of Stanford Splash, which brings middle and high school students to campus to learn from Stanford students. Vivian has taught Splash courses since 2014. Her most recent course was "Sewable Electronics."

Vivian has also been a teaching assistant for two of the department's most popular courses, "An Intro to Making: What is EE" and "Digital Systems Design". She was selected through a competitive process, to be a peer tutor in math and physics. Vivian also participated in EE's REU program, doing research, and eventually co-authoring a paper with Professor Jim Harris. Vivian has also worked as an undergraduate research assistant for Professor Amin Arbabian.

"I am grateful for the research and other experiences Stanford has provided me thus far and look forward to the scientific and cultural opportunities provided through the Churchill Scholarship," Wang said.

The goal of the Churchill Scholarships program, established at the request of Sir Winston Churchill, is to advance science and technology on both sides of the Atlantic, helping to ensure future prosperity and security.

Professor Shanhui Fan has been selected to receive the 2017 Vannevar Bush Faculty Fellowship.

"The fellowship program provides research awards to top-tier researchers from U.S. universities to conduct revolutionary "high risk, high pay-off" research of strategic importance to the Department of Defense," said Mary J. Miller, acting assistant secretary of defense for research and engineering.

Fellows conduct basic research in core science and engineering disciplines that underpin future DoD technologies, such as, quantum information science, neuroscience, nanoscience, novel engineered materials, applied mathematics, statistics, and fluid dynamics. Fellows directly engage with the DoD research enterprise to share knowledge and insights with DoD civilian and military leaders, researchers in DoD laboratories, and the national security science and engineering community.

"Grants supporting the program engage the next generation of outstanding scientists and engineers in the "hard" problems that DoD needs to solve," Miller said.

DoD congratulates each of these remarkable scientists and engineers on selection as Vannevar Bush Faculty Fellows, bringing the current cohort to 45 Fellows.

 

Please join the department in congratulating Shanhui for this well deserved recognition and support of his outstanding research!

Congratulations to Isha Datye and Alexander Gabourie on their winning poster, "Reduction of hysteresis in MoS2 transistors using pulsed voltage measurements". 

 

The Device Research Conference (DRC) brings together leading scientists, researchers, and students to share their latest discoveries in device science, technology and modeling. 2016 marked the 75th anniversary of the DRC — the longest running device research meeting in the world.

 

Abstract

Transistors based on atomically thin two-dimensional (2D) materials like MoS2 have attractive properties for applications in low-power electronics. However, in practice their electrical measurements often exhibit hysteresis, masking their intrinsic behavior. In this study we used pulsed measurements to decrease hysteresis, examine charge trapping, and extract device parameters (like mobility) that represent the "true" behavior of 2D devices. Hysteresis is minimized even with modest ≤ 1 ms pulses, and the extracted mobility converges to a unique value, unlike the less reliable conventional methods which rely either on forward or reverse DC sweeps.

Ning Wang, EE PhD candidate, received best paper and best poster awards at TECHCON 2016. The title of his paper is "GDOT: A Graphene-Based Nanofunction for Dot-Product Computation".

TECHCON is a technical conference and networking event for Semiconductor Research Corporation (SRC) members and students.

Ning Wang's research is in Physical Technology & Science and his advisor is Eric Pop.

 

Congratulations to Ning on his well-deserved recognition!

 

Abstract
Though much excitement surrounds two-dimensional (2D) beyond CMOS fabrics like graphene and MoS2, most efforts have focused on individual devices, with few high-level implementations. Here we present the first graphene-based dot-product nanofunction (GDOT) using a mixed-signal architecture. Dot product kernels are essential for emerging image processing and neuromorphic computing applications, where energy efficiency is prioritized. SPICE simulations of GDOT implementing a Gaussian blur show up to ~10(4) greater signal-to-noise ratio (SNR) over CMOS based implementations - a direct result of higher graphene mobility in a circuit tolerant to low on/off ratios. Energy consumption is nearly equivalent, implying the GDOT can operate faster at higher SNR than CMOS counterparts while preserving energy benefits over digital implementations. We implement a prototype 2-input GDOT on a waferscale 4" process, with measured results confirming dot-product operation and lower than expected computation error.

Abstract:
FPGAs are a popular target for application-specific accelerators because they lead to a good balance between flexibility and energy efficiency. However, FPGA lookup tables introduce significant area and power overheads, making it difficult to use FPGA devices in environments with tight cost and power constraints. This is the case for datacenter servers, where a modestly-sized FPGA cannot accommodate the large number of diverse accelerators that datacenter applications need.

This paper introduces DRAF, an architecture for bit-level reconfigurable logic that uses DRAM subarrays to implement dense lookup tables. DRAF overlaps DRAM operations like bitline precharge and charge restoration with routing within the reconfigurable routing fabric to minimize the impact of DRAM latency. It also supports multiple configuration contexts that can be used to quickly switch between different accelerators with minimal latency. Overall, DRAF trades off some of the performance of FPGAs for significant gains in area and power. DRAF improves area density by 10x over FPGAs and power consumption by more than 3x, enabling DRAF to satisfy demanding applications within strict power and cost constraints. While accelerators mapped to DRAF are 2-3x slower than those in FPGAs, they still deliver a 13x speedup and an 11x reduction in power consumption over a Xeon core for a wide range of datacenter tasks, including analytics and interactive services like speech recognition.

 

Congratulations to Mingyu and co-authors. His research advisor is Christos Kozyrakis
