Assistant Professor Kioupakis

The MSE department welcomes Manos Kioupakis, who has joined the faculty as an assistant professor.   

Kioupakis uses parallel first-principles computational methods and high-performance computing to study the structural, electronic and optical properties of materials at the atomic scale.

With a bachelor's degree in physics from the University of Crete and a doctorate in condensed matter physics from University of California at Berkeley, Kioupakis conducted postdoctoral work in the Materials department at the University of California at Santa Barbara. During that time, he developed a set of first-principles computational tools to study the energy loss mechanisms in nitride optoelectronic devices. Using these techniques he discovered the primary efficiency loss mechanism of nitride-based light-emitting diodes at the high powers that general lighting requires: Auger recombination, a three-carrier non-radiative recombination mechanism that dominates at high carrier densities.[1] He also found that the internal loss in nitride lasers is due to the internal reabsorption of light by holes bound to non-ionized magnesium atoms in the p-type layers of the device.[2] His findings enabled him to propose ways to reduce the impact of these loss mechanisms and improve device efficiency.

At UM, Kioupakis plans to continue working to understand, model, predict and optimize the properties of new electronic, optoelectronic, photovoltaic and thermoelectric materials. In particular, he plans to apply his theoretical insights to investigate promising new materials and photon-to-electricity conversion concepts in order to help develop next-generation photovoltaic devices for solar electricity applications. He also hopes to investigate the thermoelectric behavior of novel materials and uncover new materials with enhanced thermoelectric properties for energy applications. 

Kioupakis is looking forward to beginning his appointment. "I'm thrilled to be joining the outstanding students and faculty at UM and to be able to use its top-notch research facilities."
