Improving Off-State Breakdown Voltage of a Double-Channel AlGaN/GaN HEMT with Air-Bridge Field Plate and Slant Field Plate

Design of normally-off GaN-based T-gate with Drain-Field-Plate (TGDFP) HEMT for power and RF applications

In this paper, an effective T-gate with Drain-Field-Plate (TGDFP) technology is used in GaN-based HEMT for high breakdown voltage of 500V and drain current of 540mA/mm. Silvaco TCAD simulation showed that normally-off TGDFP HEMT with recessed gate length of 0.5μm exhibited high threshold voltage up to +1V and transconductance of 140mS/mm along with frequency operation in Sband (∼3GHz). The prop...

Effect of Variable Thermal Conductivity and the Inclined Magnetic Field on MHD Plane Poiseuille Flow in a Porous Channel with Non-Uniform Plate Temperature

The aim of this paper is to investigate the effect of the variable thermal conductivity and the inclined uniform magnetic field on the plane Poiseuille flow of viscous incompressible electrically conducting fluid between two porous plates Joule heating in the presence of a constant pressure gradient through non-uniform plate temperature. It is assumed that the fluid injection occurs at lower pl...

Double-Pass Flat-Plate Solar Air Heaters with External Recycle

A new device of inserting an absorbing plate to divide a flat-plate channel into two channels with fins attached and external recycling at the ends, resulting in substantially improving the heat transfer efficiency, has been investigated both experimentally and theoretically. The agreement of the theoretical predictions with those measured values from the experimental results is fairly good. Th...
