About

Karthik Shankar received his B.Tech degree in 2000 from the Indian Institute of Technology-Madras, India, where he was awarded the prestigious Governor’s Gold Medal for all-round excellence from his graduating class. Karthik Shankar was an Eastman Kodak Research Fellow in 2003. He received his M.S. and Ph.D. degrees in Electrical Engineering at Penn State University. He joined the department of Electrical & Computer Engineering at the University of Alberta as an Assistant Professor in the Fall of 2009. He is the author of 35 papers in refereed journals and has delivered numerous talks at major international conferences such as the Meetings of the Materials Research Society, the SPIE, the Device Research Conference and the Electronic Materials Conference. He is also listed as an inventor on two provisional patents. In 2010, he received the PetroCanada Young Innovator Award.

Research

Dr. Shankar’s research interests include the growth of nanotube and nanowire arrays in inorganic and organic semiconductors; the characterization of the optoelectronic properties of nanoscale materials; and the use of nanostructured materials to improve the performance of photovoltaic devices, thin film transistors and light emitting diodes. He is also interested in excitonics; colloidal quantum dots, quantum wires and π-conjugated molecules are excitonic semiconductors, due to which the understanding and control of excitonic creation and annihilation, migration, delocalization, coherence and dissociation are of fundamental importance. A major theme of his research is the understanding and exploitation of phenomena unique to nanotube and nanowire arrays, which originate in their spatial configuration, their size confinement and their anisotropy. He is also pursuing applications for semiconducting nanotube and nanowire arrays in catalysis and biology.
