Surface passivation for semiconductor devices and electroluminescent cooling
The Finnish Research Impact Foundation
Aalto University
Surface defects play a role in essentially all semiconductor devices. In SuperDevice we study the use of the controlled oxidation developed by Comptek Solutions Oy in eliminating the detrimental surface recombination in thermophotonic GaAs based optical cooler prototypes investigated at Aalto University. This enables a case study of using controlled oxidation in state-of-the-art compound semiconductor devices, potentially eliminating one of the key bottle-necks presently slowing down the development of optical cooling technologies that may later on revolutionize solid state as well as general cooling applications.
