Abstract
Nonlinear transport properties of Y-branched semiconductor nanostructures were studied in the non-linear transport regime. The Y-branch switches (YBSs) were defined by electron beam lithography and wet etching techniques in modulation doped GaAs/AlGaAs heterostructures. Due to capacitive couplings between different branches, YBSs can be used as amplifiers, inverters, bistable switches and compact logic gates with functional integration. Room temperature operation of a logic gate with gain solely based on coupled YBSs without external load resistors is reviewed.
