Room-temperature operation of a logic NOR gate is demonstrated. The NOR gate is based on three three-terminal junctions (TTJs) monolithically integrated in a modulation-doped GaAs/AlGaAs heterostructure without any external load resistance. For the logic NOR gate, one of the TTJs serves as load transistor, whereas the other two are used as inputs. Each TTJ has a 90-nm-wide channel and shows clear transistor characteristics with drain currents up to 10 mu A for a drain voltage of 1 V. Furthermore, voltage amplification is demonstrated for the logic NOR-gate function.
