Abstract
The electronic transport properties of individual GaN nanowire configured as field-effect transistors (FETs) show them to be highly conductive n-type semiconductors. Accordingly, the source-drain current (ISD) of these FETs cannot be varied significantly by the gate potential. When doped with Mn by thermal diffusion, the carrier density of resultant nanowire drops approximately two orders of magnitude likely due to the fact that Mn doping produces deep acceptor states that compensate for the native shallow donors of as-grown GaN nanowires. The ISD of the Mn-doped GaN nanowires could be modulated by a factor of 5 using the gate potential.
