"ESNL is working to provide efficient and reliable solid state devices to convert waste heat and solar energy to usable electrical energy."
Mona Zebarjadi, Assistant Professor
Mona Zebarjadi is a joint professor of Electrical and Computer Engineering and Materials Science and Engineering Departments at University of Virginia, where she is leading the Energy Science and Nanotechnology Lab (ESNL). Prior to her current appointment she was a professor of Mechanical Engineering Department 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 and master's degree in physics from Sharif University 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 is the recipient of 2017 NSF Career award, 2014 AFOSR career award, 2015 A.W. Tyson assistant professorship award, MRS graduate student gold medal, and SWE electronics for imaging scholarship.

In 1965, Intel co-founder Gordon Moore noticed that the number of transistors per square inch of integrated circuit doubled roughly every two years. Moore’s Law posits that this trend would continue into the foreseeable future — and it has. Certainly the ability to hold a smartphone in the palm of your hand — in the process availing yourself of the computing power of a circa-1990 supercomputer — is a testament to Moore’s prescience.
Thermoelectric devices — which can either generate an electric current from a difference in temperature or use electricity to produce heating or cooling without moving parts — have been explored in the laboratory since the 19th century. In recent years, their efficiency has improved enough to enable limited commercial use, such as in cooling systems built into the seats of automobiles. But more widespread use, such as to harness waste heat from power plants and engines, calls for better materials.
The design of artificial metamaterials that allow “cloaking”—apparent invisibility to acoustic and electromagnetic waves—is more than a party trick. Many applications suggest themselves if one could create cloaking at useful frequencies or in technologically relevant systems. Writing in Physical Review Letters, Bolin Liao and colleagues at Massachusetts Institute of Technology, Cambridge, propose the use of cloaking in semiconductor devices to optimize electron mobility in nanostructured materials.
