Inserting a low-temperature n-GaN underlying layer to separate nonradiative recombination centers improves the luminescence efficiency of blue InGaN/GaN LEDs
We have investigated the effects of nonradiative recombination centers (NRCs) on the device performance of InGaN/GaN multi-quantum-well (MQW) light-emitting diodes (LEDs) inserting low-temperature n-GaN (LT-GaN) underlying [...]
PAM-XIAMEN can provide wafer polishing service for III-V compound wafers (such as InSb wafer, GaSb wafer, InAs wafer), ultra-thin semiconductor wafer, CZT wafer and other photoelectric materials. We aim to adopt a high-precision chemical polishing process to minimal surface damage. Take the InSb wafer [...]
