COMMON DRAIN BIDIRECTIONAL SWITCH

Abstract: a bidirectional switch for use in high power electronics, being compact and having low on-resistance. the bidirectional switch includes several layers epitaxially grown on a substrate, the epitaxial layer comprising a channel layer and a barrier layer grown on the channel layer, an interface of the barrier layer and the channel layer defining a heterojunction that induces a two-dimensional electron gas (2deg) within the channel layer, the 2deg extending laterally at the interface between the barrier and channel layers. the bidirectional switch includes two source contacts, which are ohmic, each in contact with the 2deg channel layer, but near opposite ends of the 2deg. the bidirectional switch further includes two gate electrodes disposed over the barrier layer and between the two source contacts. voltages applied to these gate electrodes controls the current flow in the bidirectional switch between the two contacts.
