A transistor according to the invention for simultaneously providing at least two current-voltage characteristics includes a base, a collector, and an emitter. At least one of the base, collector, and emitter includes a first layer grown using molecular beam epitaxy (MBE). The first layer includes a first strip having a first doping characteristic created using focused ion beam processing. A second strip has a second doping characteristic created by focused ion beam processing. A middle section of undoped material is located between the first and second strips. A resonant tunneling junction is grown on the first layer using MBE and includes a plurality of layers.
