Abstract
A transistor device and method of making the same, the transistor device including: a substrate; a word line disposed on the substrate; a gate insulating layer disposed on the word line; a dual-layer semiconductor channel including: a first channel layer disposed on the gate insulating layer; and a second channel layer disposed on the first channel layer, such that the second channel layer contacts side and top surfaces of the first channel layer; and source and drain electrodes electrically coupled to the second channel layer. When a voltage is applied to the word line, the first channel layer has a first electrical resistance and the second channel layer has a second electrical resistance that is different from the first electrical resistance.
