ZnO/Si SAW convolver with surfacehyphen;controlling junctions

摘要

A new type of ZnO/Si monolithic convolver has been constructed for the purpose of eliminating unstable memory effects due to the traps in ZnO or due to the SiO2/Si interface states. It has controllingp‐njunctions on the Si surface. It was experimentally verified that by varying the junctions bias, the convolution output can be controlled with a rapid response time and without any hysteresis. The applications of this device to a matched filter have been also demonstrated.
