We report here the lateral epitaxial overgrowth (LEO) of GaN on a patterned GaN-on-silicon substrate by molecular beam epitaxy (MBE) growth with radio frequency nitrogen plasma as a gas source. Two kinds of GaN nanostructures are defined by electron beam lithography and realized on [...]

What is silicon made of?
Silicon is made from silicon dioxide, or silica – found in nature as quartz, or common beach sand.
First, the silica is put into a Silicon Furnace, where a carbon electrical arc reacts at high temperatures to drive the oxygen out [...]

We designed and fabricated AlGaN/GaN high-electron-mobility transistors (HEMTs) employing both a floating gate (FG) and a field plate (FP), which increase the breakdown voltage of AlGaN/GaN HEMTs significantly without sacrificing forward electric characteristics. The electric field strength at the gate–drain region of the proposed [...]
