Classification: CPC H | IPC H

Claim 0:
1. A single-gate field effect transistor device, comprising an active layer, a source region and a drain region formed on two sides of the active layer, and a channel region located between the source region and the drain region; wherein the field effect transistor device is configured such that:
a depletion-mode second channel is spontaneously formed in the channel region when the transistor is turned off, the second channel does not connect the source region with the drain region; and
the second channel and a first channel which has the same polarity as the second channel are formed in the channel region when the transistor is turned on; wherein at least one of the first channel and the second channel injects carriers into the other channel such that the source region and the drain region are in electrical connection with each other, and carriers of the second channel contribute to the on-state current of the transistor.
