A model for in-plane-gated structures is proposed, taking into account surface currents and surface charges. The lateral band structures and barrier heights are calculated selfconsistently for different bias voltages utilizing this new model. Accumulated negative surface charges lead to a strongly i
In-plane-gate (IPG) transistors have been fabricated using focused ion beam implantation doping of GaAs=In0:1Ga0:9As= Al0:35Ga0:65As heterostructures. At room temperature in the dark, the devices show good transistor characteristics and-in contrast to IPG transistors deΓΏned by insulation writing usi
