Suppressing Buffer-Induced Current Collapse in GaN HEMTs with a Source-Connected p-GaN (SCPG): A Simulation Study

Novel GIT Structure Solves Current Collapse In GaN Power HEMTs

The advantage of GaN power devices in terms of performance is no longer hype but a reality that has empowered many power supply designers to build new applications that are more efficient, compact and able to operate in harsher environmental conditions. With a projected market size of U.S. $600 million in 2020 and a CAGR of 80% to 2020, many new players have entered the field and are introducin...

atedA GaN/GaN HEMTs

Two simple class-F NVI1VIIC power amplifiers are described using 0.7tm field-plated GaN HEMT devices. One circuit was designed for operation at 2.0 GHz and achieved a power-added-efficiency of 50%, 38 dBm output power, and 6.2 W/mm power density. A second circuit was designed at 2.8 GHz and achieved a PAE of 46% with 37 dBm output power and 7.0 W/mm power density.

Normally-Off InAlN/GaN HEMTs with n GaN Cap Layer: A Simulation Study

The ongoing interest in the development of GaN-based enhancement-mode high electron mobility transistors (EHEMTs) resulted in several different approaches being proposed, one of them employing a reduction of the gate-to-channel distance. In order to facilitate gate recessing, a technique using a n++ cap layer was suggested by Kuzmik et al. [1], who also analyzed the contribution of the cap laye...

Electrical Performances of AlInN/GaN HEMTs. A Comparison with AlGaN/GaN HEMTs with similar technological process

Improved InGaN/GaN light-emitting diodes with a p-GaN/n-GaN/p-GaN/n-GaN/p-GaN current-spreading layer.

This work reports both experimental and theoretical studies on the InGaN/GaN light-emitting diodes (LEDs) with optical output power and external quantum efficiency (EQE) levels substantially enhanced by incorporating p-GaN/n-GaN/p-GaN/n-GaN/p-GaN (PNPNP-GaN) current spreading layers in p-GaN. Each thin n-GaN layer sandwiched in the PNPNP-GaN structure is completely depleted due to the built-in ...
