A gated resonant tunneling diode (GRTD) that operates without cryogenic cooling is provided. This GRTD employs conventional CMOS process technology, preferably at the 65 nm node and smaller, which is different from other conventional quantum transistors that require other, completely different process technologies and operating conditions. To accomplish this, the GRTD uses a body of a first conduction type with a first electrode region and a second electrode region (each of a second conduction type) formed in the body. A channel is located between the first and second electrode regions in the body. A barrier region of the first conduction type is formed in the channel (with the doping level of the barrier region being greater than the doping level of the body), and a quantum well region of the second conduction type formed in the channel. Additionally, the barrier region is located between each of the first and second electrode regions and the quantum well region. An insulating layer is formed on the body with the insulating layer extending over the quantum well region and at least a portion of the barrier region, and a control electrode region is formed on the insulating layer.
