The growth of information technology has been sustained by the miniaturization of Complementary Metal-Oxide-Semiconductor (CMOS) Field-Effect Transistors (FETs), with the number of devices per unit area constantly increasing, as exemplified by Mooreâs la ...
GaN-based electronic devices have great potential for future power applications, thanks to their wide band-gap, high breakdown electric field, and high electron mobility. In addition, these devices can be integrated on large-size Si substrates and enable n ...
In this letter, we present a new concept for normally-off AlGaN/GaN-on-Si MOS-HEMTs based on the combination of p-GaN, tri-gate and MOS structures to achieve high threshold voltage (V-TH) and low on-resistance (R-ON). The p-GaN is used to engineer the band ...
Field-effect transistors (FETs) have established themselves as a leading platform for electrical detection of chemical and biological species. Their advantages over other optical, mechanical sensing platforms are attributed to being miniaturizable, mechani ...
