Growth Mechanism of GaAs Microdisk Structures by Area-Selective Epitaxy Using Migration-Enhanced Epitaxy

Growth Mechanism of GaAs Microdisk Structures by Area-Selective Epitaxy Using Migration-Enhanced Epitaxy We have carried out area-selective epitaxy of GaAs microdisk structures on a SiO2-masked GaAs substrate by migration-enhanced epitaxy. We have successfully grown “damage-free” disks at 590 °C. It is found that, for the structures grown on (111)B substrates, [...]

The SiC and GaN power semiconductor market will exceed $10 billion by 2027!

The SiC and GaN power semiconductor market will exceed $10 billion by 2027! Key conclusions: Emerging-market silicon carbide(SiC) and gallium nitride(GaN) power semiconductors are expected to reach nearly $1 billion by 2020, driven by demand for hybrid and electric vehicles, power and photovoltaic (PV) inverters. The use of SiC and GaN power [...]

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 kWh) and 2% of total [...]

Near-band-edge luminescence in heavily doped gallium arsenide

Near-band-edge luminescence in heavily doped gallium arsenide The near-band-edge photoluminescence at 80K of heavily tellurium-doped degenerate liquid-phase-epitaxial gallium arsenide layers (n=2*1018 cm-3) is investigated. The layers are compensated with shallow germanium acceptors (the values of the degree of compensation are K=0.05-0.7) during the epitaxial growth process. It is established that even [...]
