ABSTRACT
Electron Y-branch switches (YBSs) were fabricated in modulation-doped GaAs/AlGaAs heterostructures by electron-beam lithography and etching techniques. The YBS is controlled by two lateral sidegates. Feedback coupling of one of the branches to the adjacent sidegate leads to a pronounced switching bistability when varying the voltage at the other sidegate. This mode of operation is associated with a Schmitt-Trigger-like switching hysteresis of up to 135 mV.
