![]() ![]() The source and drain connect directly to the GaN layer, while the gate sits on the AlGaN layer. Just like any FET structure, dGaN has three electrodes Gate, source, and drain. It works like a MOSFET, with a positive bias across its gate relative to source turns on the device. Depletion mode GaN (dGaN) HEMT works in always-on mode and a negative voltage is applied across the gate relative to the drain and source to turn it off whereas Enhancement mode GaN (eGaN) HEMT works in always-off mode. GaN HEMT is available in enhancement and depletion modes. GaN HEMT is a high electron mobility transistor, and it utilizes the HEMT structure with its two-dimensional electron gas (2DEG) region providing the fundamental mode of operation for the device. Typically, GaN is deposited on either silicon or silicon carbide to give GaN on Silicon, often referred to as Gan on Si, or GaN on Silicon carbide referred to as GaN on SiC. ![]() The remarkably high electron mobility of gallium nitride (GaN) enables the fabrication of transistors that have a low value of ON resistance combined with a very high switching frequency capability. With conventional devices such as MOSFETs reaching their theoretical limits in terms of speed, efficiency, and performance, GaN FETs provide a spectrum of better performance characteristics and hence are rapidly being adopted as the next-gen power-switching device by the industry. ![]() GaN HEMT or GaN FET power devices are quickly emerging as an alternative to other power devices such as silicon-based MOSFETs, and IGBTs owing to their better performance in terms of speed, efficiency, form factor, operating temperature, and other parameters.
