Research interests: modelling and computer simulations for emerging devices; quantum transport in low dimensional materials such as graphene


Professor Youngki Yoon’s research group focuses on understanding physics of non-equilibrium phenomena in nanosystems with relevance to device applications by means of modeling and simulations. Building on rigorous fundamental understanding, he has developed his own quantum transport simulator using Non-Equilibrium Green’s Function (NEGF) method. Atomistic simulations may enable predictive analysis of nanoscale devices for which direct experimental investigation can often be extremely challenging and prohibitively expensive.

He received his Ph.D. in Electrical and Computer Engineering from the University of Florida (Gainesville, FL) in 2008, where his research mainly focused on ballistic transport in carbon nanotube devices. Then he worked as a postdoctoral research at the University of California, Berkeley where he has done pioneering work in the field of non-equilibrium quantum transport, including the first demonstration of dissipative simulation using the NEGF formalism for the realistic size of devices (>200 nm) and the first-ever trial that included both phonon and roughness scattering for graphene nanoribbon transistors.
