Youngki Yoon

Dr. Youngki Yoon is an Associate Professor in the Department of Electrical and Computer Engineering at the University of Waterloo. His research focuses on understanding the physics of non-equilibrium phenomena in nanosystems, with particular relevance to device applications, using modeling and simulations. Building on a rigorous fundamental understanding, Dr. Yoon has developed his own quantum transport simulator based on the Non-Equilibrium Green’s Function (NEGF) method. His atomistic simulations enable predictive analysis of nanoscale devices, providing insights where direct experimental investigation is often extremely challenging and prohibitively expensive.

Dr. Yoon earned his Ph.D. in Electrical and Computer Engineering from the University of Florida, Gainesville, in 2008, where his research primarily focused on ballistic transport in carbon nanotube devices. He then worked as a postdoctoral researcher at the University of California, Berkeley, where he made pioneering contributions to non-equilibrium quantum transport. His work included the first demonstration of dissipative simulations using the NEGF formalism for realistic device sizes (>200 nm) and the first-ever attempt to incorporate both phonon and roughness scattering in graphene nanoribbon transistors.
