InGaN/GaN Multi-Quantum-Well and Light-Emitting Diode Based on V-pit-Shaped GaN Grown on Patterned Sapphire Substrate
Lai Wang, Xiao Meng, Di Yang +8
V-pit-defects in GaN-based light-emitting diodes induced by dislocations are considered beneficial to electroluminescence because they relax the strain in InGaN quantum wells and a…
"WM"-Shaped Growth of GaN on Patterned Sapphire Substrates
Lai Wang, Xiao Meng, Di Yang +7
In metal organic vapor phase epitaxy of GaN, the growth mode is sensitive to reactor temperature. In this study, V-pit-shaped GaN has been grown on normal c-plane cone-patterned sa…
Understanding different efficiency droop behaviors in InGaN-based near-UV, blue and green light-emitting diodes through differential carrier lifetime measurements
Lai Wang, Xiao Meng, Jiaxing Wang +7
Efficiency droop effect under high injection in GaN-based light emitting diodes (LEDs) strongly depends on wavelength, which is still not well understood. In this paper, through di…
A PMT-like high gain avalanche photodiode based on GaN/AlN periodical stacked structure
Ji-yuan Zheng, Lai Wang, Di Yang +18
Avalanche photodiode (APD) has been intensively investigated as a promising candidate to replace photomultiplier tubes (PMT) for weak light detection. However, in conventional APDs…
