MEMS pressure sensor with an AlGaN/GaN based high electron mobility transistor

Vanko G., Dzuba J., Rýger I., Vallo M., Institute of Electrical Engineering, SK

The III Nitrides (III-N), especially gallium nitride (GaN) and its compounds, are very attractive for pressure and strain sensing thanks to their excellent piezoelectric properties. The AlGaN/GaN heterostructure offers high mechanical and chemical stability, operation [...]

Fabrication of pyramid array nanostructure on gallium nitride

Hsieh C-C, Ke W.C., Chen N-P, Cheng Y.C., Lin J.C., Lin W.J., Cheng Y.C., Li T-C, Lin J.C., Lin W.J., Lin J.C., Lin W.J., Yuan Ze University, TW

GaN has relatively high refractive index and results in low light extraction efficiency in photonics applications. A novel way to combine the various methods to enhace the efficiency is to construct a pyramid array on [...]

Gallium Nitride Nanowire Enhanced High Intensity Discharge Luminance System

Tsai J.T.H., Liao Z.-J., Tatung University, TW

We produce an mercury-free, high efficiency HID lamp with the GaN nanostructure enhancer embedded. These dense GaN nanowires embedded into the HID electrodes can reduce 25% of ignition voltage and enhance the 17% of efficiency [...]
