In light of the ongoing coronavirus (COVID-19) situation, we have decided to close our administrative offices starting Monday, March 16, through Tuesday, April 7, 2020.  EECS administrative reception offices will be closed (253 Cory Hall and 387 Soda Hall) and building access will be restricted to those who have card keys.  Classes are being held remotely.  All events in Cory and Soda Halls with either be cancelled or held remotely, and staff will be working remotely during this time.

Students create online "Coronavirus Tracker" to keep average Americans informed

CS major Jason (XiangJun) Li and a few friends have developed a website designed to provide clear, reliable, up-to-date numbers and trends on the COVID-19 outbreak "for average Americans," particularly those on mobile phones.  LiveCoronaUpdates.org, which was launched last Tuesday, uses data released by the World Health Organization and official government websites, and provides "the simplest and most intuitive dashboard for people to quickly understand the trends and assess risks."  The site includes domestic and global numbers of patients confirmed/recovered/dead, simple graphics and tables, a headline feed, and text alerts using data that is updated every 3 hours.

Chenming Hu donates IEEE Medal of Honor winnings to EECS department

EE Prof. and alumnus Chenming Hu (M.S. '70, Ph.D. '73), who won the 2020 IEEE Medal of Honor, has chosen to donate his $50K prize to the EECS department.   Hu, who was cited “for a distinguished career of developing and putting into practice semiconductor models, particularly 3D device structures, that have helped keep Moore’s Law going over many decades," is also the subject of an IEEE Spectrum article.  He was hired on the Berkeley faculty in 1976 and has been called the "Father of the 3D Transistor" due to his development of the Fin Field Effect Transistor in 1999.  Intel, the first company to implement FinFETs in its products, called the invention the most radical shift in semiconductor technology in more than 50 years.

Women In Tech at Berkeley

The 4th Annual Women In Tech Symposium, part of the Women In Tech Initiative (WITI) will be held at UC Berkeley on Friday, March 6, 2020.  The theme will be "Reimagining Cybersecurity for All."  Many members of the EECS community will be involved, including: alumna and Prof. Dawn Song (PhD '02) - opening remarks; WITI@UC co-founder and dean of Engineering Prof. Tsu-Jae King Liu - fireside chat; Prof. Raluca Ada Popa - Panel: What’s at Stake? Global and Systemic Cyber Threats;  and CITRIS Director Prof. Costas Spanos - Athena Awards presentation. Tickets will be available until Monday, March 2nd.

Microrelays: On the path to making bigger quantum computers

Research on Microrelays presented at the IEEE International Electron Devices Meeting (IEDM) by Prof. Tsu-Jae King Liu and alumna/graduate student, Xiaoer Hu (M.S. '18), is highlighted in an IEEE Spectrum article titled "4 Ways to Make Bigger Quantum Computers."  It is difficult to scale quantum computers because quantum-computer processors must operate inside cryogenic enclosures at near absolute zero, but the electronics needed for readout and control don’t work at such temperatures and must reside outside the refrigerator.  King Liu and Hu have developed micrometer-scale electromechanical relays as ultralow-power alternatives to transistors that operate better when cooled to 4 kelvins than at room temperature.  Freezing temperatures solve two of the mechanical problems the devices encounter:  the reaction of ambient oxygen on electrode surfaces, and the way that microscale relays tend to stick together.  “We didn’t suspect ahead of time that these devices would operate so well at cryogenic temperatures,” says King Liu. “In retrospect, we should have.”

Negative Capacitance research highlighted in celebration of 100 Years of Ferroelectricity

Negative Capacitance, a field of research pioneered by EECS Prof. Sayeef Salahuddin, is featured in a Nature Materials article celebrating "A century of ferroelectricity."  Ferroelectricity is a characteristic of certain materials which have a spontaneous electric polarization that can be reversed by the application of an external electric field. Ferroelectric capacitors are used in sensor applications, like Ultrasound.  To highlight examples of recent advances in the field, the article references a 2008 paper co-written by Salahuddin, which proposed that negative capacitance could be used to provide voltage amplification and was observed in thin ferroelectric films.

Researchers develop novel way to shrink light to detect ultra-tiny substances

EE Associate Prof. Boubacar Kanté and his graduate student Junhee Park have been profiled in a Berkeley Engineering article titled "Researchers develop novel way to shrink light to detect ultra-tiny substances."  They are part of a team of researchers who have created light-based technology that can detect biological substances with a molecular mass more than two orders of magnitude smaller than previously possible.  Their device, which would shrink light while exploiting mathematical singularities known as exceptional points (EP), could lead to the development of ultra-sensitive devices that can quickly detect pathogens in human blood and considerably reduce the time needed for patients to get results from blood tests. Their work was published in Nature Physics last week. “Our goal is to overcome the fundamental limitations of optical devices and uncover new physical principles that can enable what was previously thought impossible or very challenging,” Kanté said.

Keeping classified information secret in a world of quantum computing

Computer Science and Global Studies double major, Jake Tibbetts, has published an article in the Bulletin of the Atomic Scientists titled "Keeping classified information secret in a world of quantum computing."  Tibbetts, who is a research assistant at the LBNL Center for Global Security Research and a member of the Berkeley Nuclear Policy Working Group, argues that instead of worrying about winning the quantum supremacy race against China, U.S. policy makers and scholars should shift their focus to a more urgent national security problem: How to maintain the long-term security of secret information secured by existing cryptographic protections, which will fail against an attack by a future quantum computer.  Some possible avenues include deploying honeypots to misdirect and waste the resources of entities attempting to steal classified information; reducing the deployment time for new encryption schemes; and triaging cryptographic updates to systems that communicate and store sensitive and classified information.

New nonvolatile memory cells shrink circuits and speed searches

The work of Prof. Sayeef Salahuddin and grad student Ava Tan is featured in an article in the IEEE Spectrum titled "New Nonvolatile Memories Shrink Circuits That Search Fast."  Salahuddin, a ferroelectric device pioneer, has been conducting work on a new kind of content-addressable memory cell that could speed searches and enable in-memory computing.   The new nonvolatile memory, which is smaller and potentially much more dense than other experimental designs, relies on ferroelectric field-effect transistors (FeFETs), which store data as an electric polarization within the transistor.

Leon Chua wins 2020 Julius Springer Prize

Prof. Emeritus Leon O. Chua has been awarded the 2020 Julius Springer Prize for Applied Physics.  Chua has contributed to cellular neural and nonlinear networks, nanoelectronics, nonlinear circuits and systems, nonlinear dynamics, bifurcation theory, and chaos theory. In 1971, he postulated a passive component named the memristor as the 4th passive electronic device derived from fundamental considerations.  37 years later, this device--with as predicted electrical characteristics--was experimentally found by a team at HP in 2008.  The award, which recognizes researchers who have made an outstanding and innovative contribution to the field of applied physics, comes with a prize of $5K and will be presented at the Magnus-Haus in Berlin, Germany on 18 September 2020.  The presentation will be accompanied by a public lecture given by Chua.
