Abstract : The purpose of this AASERT grant was to extend the work on resonant tunneling devices to include a new structure which has shown evidence of zero-bias memory switching and multi-state behavior. This device is known as a quantum storage device or QSD. This device features a triple barrier resonant tunneling device, yielding a three terminal device. Under the AASERT, extensive simulations were performed using the Schrodinger-Poisson and Wigner formalisms. Optimization of the QSD design to achieve high on-off resistance ratios is a main focus of the parameter study. Results to date will be described.
