Wide Bandgap Technology –Next Generation Power Devices
Wide Bandgap Technology –Next Generation Power Devices The tightening of industry standards and changes in government regulations are key drivers of higher energy efficiency. For example, data centers are growing exponentially to meet demand. They use about 3% of the world’s total electricity supply (400 [...]
Low Temperature GaAs
(LT-GaAs)Experimental Results PAM XIAMEN offers Low Temperature GaAs. Preparation for pump & probe measurement Reflectance spectra measurement : we could not observe the reflectance peak. PL spectra measurement : PL spectra were observed between 810 and 845 nm. Pump & probe measurement (10 K) ・We have observed 0.6-1.6 picosecond decay [...]
Stress in (Al, Ga)N heterostructures grown on 6H-SiC and Si substrates byplasma-assisted molecular beam epitaxy
The paper describes experimental results on low temperature plasma-assisted molecular beam epitaxy of GaN/AlN heterostructures on both 6H-SiC and Si(111) substrates. We demonstrate that application of migration enhanced epitaxy and metal-modulated epitaxy for growth of AlN nucleation and buffer layers lowers the screw and [...]
What is Carrier Mobility?
Carrier mobility is often used to refer to the overall movement of electrons and holes in semiconductors. Mobility refers to the average drift velocity of carriers (electrons and holes) under the action of a unit electric field. That is a measure of the speed [...]
