EE-EP Seminar - Mona Zebarjadi, Monday, March 7th in EEB 132 @ 2:00pm

Speaker: Mona Zebarjadi, Rutgers University

Talk Title: Manipulation of Electricity and Heat at Nanoscales

Abstract: Fundamental understanding of electron and phonon transport enables us to manipulate electricity and heat at nanoscales. Advances in computations and in parallel in nanotechnology, allow design of specific quantum potentials inside materials and devices to guide charge and heat carriers. The resulting capability of manipulating electricity and heat inspires design of new electronic devices, power generators, and heat pumps. In this talk, I will discuss several examples to elucidate our approach. First I will discuss novel strategies to enhance materials carrier mobility and conductivity for design of fast transistors, switches, and thermoelectric modules via un-conventional doping schemes including 3D modulation-doping and invisible-doping. Transport modeling and experimental results on single layer graphene will be presented next as a design example of active and passive coolers. Finally, design of solid-state thermionic coolers in micron-scales (using Monte-Carlo simulations) as well as nano-scales (using first-principles modeling approach) will be described.

Biography: Mona Zebarjadi is a professor of mechanical engineering at Rutgers University. Her research interests are in electron and phonon transport modeling; materials and device design, fabrication and characterization; with emphasis on energy conversion systems such as thermoelectric, thermionic, and thermomagnetic power generators, and heat management in high power electronics and optoelectronic devices. She received her Bachelor's degree in physics from Sharif University in 2004 and her PhD in EE from UCSC in 2009, after which she spent 3 years at MIT as a postdoctoral fellow working jointly with electrical and mechanical engineering departments. She joined Rutgers University in January 2013. She is the recipient of 2014 AFOSR career award, 2015 A.W. Tyson assistant professorship award, MRS graduate student gold medal, and SWE electronics for imaging scholarship.
