NANOWIRE WRAP GATE DEVICES

摘要

The present invention provides a semiconductor device comprising at least a first semiconductor nanowire (105) having a first lengthwise region (121) of a first conductivity type, a second lengthwise region (122) of a second conductivity type, and at least a first wrap gate electrode (111) arranged at the first region (121) of the nanowire (105) in order to vary the charge carrier concentration in the first lengthwise region (121) when a voltage is applied to the first wrap gate electrode (111). Preferably a second wrap gate electrode (112) is arranged at the second lengthwise region (122). Thereby tuneable artificial junctions (114) can be accomplished without substantial doping of the nanowire (105).
