| Research Abstract |
This work presents feasibility studies for an implementation of millimeter-wave monolithic isolators by using resonant tunneling devices. We have clarified a criterion and an upper frequency limit to realize the unilateral signal transmission by using a gyrator, which consists of two resonant tunneling diodes and one high mobility transistor. Moreover, process conditions of mask-less optical lithography have been found to obtain multi-mesa and a contact layer for an electrode to be integrated.
