Transistor research based on graphene nanoribbons (Bokor and Fischer groups)
Energy-efficient electronic devices are central to the BETR Center’s research mission. Given recent advancements in cloud computing, social networking, mobile internet and data analytics, and the associated increase of battery-powered electronic systems, the development of intelligent systems that can operate at significantly reduced power consumption is now as relevant as ever. In fact, many of the ultra-low power electronics research projects in the BETR Center have originated in the Center for Energy Efficient Electronics Science (E3S) based on the recognition that the energy used to manipulate a single bit of information is currently ~100,000 times greater than the theoretical limit. Research on ultra-low power devices and circuits in the BETR Center is conducted by Professors Jeffrey Bokor, Ali Javey, Tsu-Jae King Liu, Sayeef Salahuddin, and Eli Yablonovitch, and encompasses the search for alternatives to classical transistor-based digital logic. Examples include new circuit and system architectures leveraging zero-leakage nano-electromechanical (NEM) relays, field effect transistors (FETs) with 2D materials as active layers, graphene nanoribbon transistors, and current-driven ultra-fast nanomagnetic switches.
