Dr. Christopher J. Hawley (Drexel University Department of Materials Science and Engineering)

Abstract:
We report intense,narrow-linewidth,surface chemisorption-activated and reversible ultraviolet (UV) photoluminescence from radiative recombination of the two-dimensional electron liquid with photo-excited holes at the LaAlO3/SrTiO3 interface. The switchable luminescence arises from an electron transfer-driven modification of the electronic structure via H-chemisorption onto AlO2-terminated LaAlO3,at least 2 nm away from the interface. Control of the onset of emission and its intensity are functionalities that go beyond the luminescence of compound semiconductor quantum wells. Connections between reversible chemisorption,fast electron transfer,and quantum-well luminescence suggest a new model for surface chemically reconfigurable solid-state UV optoelectronics and molecular sensing.
