Abstract:
1. A semiconductor device comprising: a channel layer formed from a semiconductor channel component material in the form of crystalline micro particles, micro rods, crystalline nano particles, or nano rods; and electrodes which are electrically coupled to the channel layer, wherein the channel layer includes at least one boundary between adjacent crystalline micro particles, micro rods, crystalline nano particles, or nano rods, each of the crystalline micro particles, the micro rods, the crystalline nano particles, or the nano rods include: wherein the at least one boundary has a lower electrical resistivity than intrinsic boundary resistivity, and wherein the channel layer has a gradient in a semiconductor dopant concentration such that, in a direction of a channel thickness, conductivity in a backchannel of the channel layer is less than conductivity in a channel of the channel layer.
