A three-terminal semiconductor device having a switching time in the vicinity of 10-12 seconds and exhibiting a dynamic negative resistance is made up of a thin barrier region in the emitter section having a barrier height that is higher than a wider barrier region in the collector section separated by a base region having a width comparable to the mean-free path length of a majority carrier. The device employs quantum mechanical tunneling as the dominant current flow mechanism from the emitter region to the base region and hot majority carrier transfer as the dominant current flow mechanism through the base region to the collector region.
