Structural Observation of Voltage Induced Transitions in Neuromorphic Devices

ORAL

Abstract

Voltage induced phase transitions in VO2 and LSMO neuromorphic devices are one pathway to next generation computing. Barrier formation in LMSO has been limited to MOKE measurements, while filament formation in VO2 devices have been observed using optical reflectivity measurements. We present a pathway to observing the structural effects of a voltage induced phase transition in these devices using dark field x-ray microscopy. In addition, preliminary observations of the barrier formation in LSMO are presented and the difficulties with performing such measurements are discussed.
