Time-resolved Study of Phase Transformation of In2Se3 Thin Films by PEEM


EMSL Project ID
24393

Abstract

This proposal is a continuation of research under EMSL User Proposal #22791. Beginning in June, 2007 this proposal is to apply EMSL 1221's photoemission electron microscopy (PEEM) to investigate the nanoscale mechanisms during phase transformation of In2Se3 induced by electrical field and/or thermal energy. PEEM allows us to follow local work function changes with the change in structure on a nano-scale in real time. The outcome of this research will ultimately help to reduce the energy to initiate the phase transformation for non-volatile memory applications. It is expected to utilize the PEEM facility for three (3) one month on-site studies during the yearly life of the proposal.
