Gallium nitride nears use in RF semiconductors

"Gallium nitride provides very high power and very high frequencies. So the power density of gallium nitride is many times that of gallium arsenide or indium phosphide. Silicon carbide can only work up to 7 to 10 GHz, and then you can't run it up any higher than that," Lynch said. Get price

Developing Ohmic Contacts to Gallium Nitride for High

A polarization

When two distinct materials are placed on top of each other, the difference in polarization between the two layers can induce charge carriers at the interface. Many such two-dimensional (2D) electron gases have been observed, but engineering a 2D hole gas without the help of doping has been much trickier. Chaudhuri et al. used molecular beam epitaxy to grow a layer of gallium nitride on top of Get price
