PhD [ECE Department, Virginia Commonwealth University, Richmond, Virginia, USA, Fall 2010 - Summer 2012]

Dissertation

Title: Hybrid spintronics and straintronics: An ultra-low energy computing paradigm
Overview: Multiferroic devices (a piezoelectric layer strain-coupled with a magnetostrictive nanomagnet) can be switched extremely energy efficiently, more so than any device currently extant, leading possibly to a new non-volatile spintronic logic and memory technology which might be an important contributor to Beyond Moore's Law technology.
