Epitaxial GaN template grown on Al2O3 (sapphire) substrate and customizable stacks are available with high quality and low defect density. Attached are a list of several types of GaN thin film on sapphire substrate wafers with different thicknesses, carrier types, and capping layers that we manufactured: 1. Specifications of GaN [...]
GaAsSb / InGaAs / InP heterostructure is provided by epi-structure MBE grower PAM-XIAMEN for optical sensor fabrication. The gallium arsenide antimonide (GaAsSb) lattice constant is completely matched with the lattice constant of InP substrate, so it is easy for epitaxial growth on InP substrate with good uniformity. The response [...]
GaN LED structure grown on nano-scale patterned sapphire (Al2O3) substrate can be provided with high efficiency of photoluminescence and electroluminescence. However, because of the high customization of the epitaxial process in the InGaN/GaN-quantum wells based LED heterostructure, we cannot get the optimal solution for patterned sapphire substrates. The design [...]
High quality GaAs based epistructures from PAM-XIAMEN – one of leading epitaxial wafer manufacturers are provided for the research, development and (potentially) later commercialization of very high efficiency light emitters for thermophotonic applications. In particular, commercially available GaAs based epi structure materials are offered long (up to micro second [...]
P-type GaN thin film epitaxial on GaN substrate is the main technique for developing emitting device. Mg is the most common p-type dopant in III-nitride material systems, partly due to the established activation process. High p-type doping of Mg concentration (1018/cm3) will be achieved in GaN when Mg dopant [...]
GaN-based light-emitting diode (LED) solid-state lighting has become the most important lighting technology in recent years because it has many advantages such as high conversion efficiency, long life, and eco-friendliness. Due to the lack of natural GaN substrates, GaN-based LED structures are usually fabricated on (0001) c-plane sapphire substrates. [...]
Hyung Koun Cho∗ Department of Metallurgical Engineering, Dong-A University, Busan 604-714 Jeong Yong Lee Department of Materials Science and Engineering, Korea Advanced Institute of Science and Technology, Daejon 305-701 We have investigated the formation of V-shaped pits in nitride films such as InGaN/GaN and AlGaN/GaN grown on sapphire substrate using transmission electron microscopy. The [...]
PAM-XIAMEN can offer AlGaAs / GaAs p-HEMT (pseudomorphic high electron mobility transistor) heterostructure epitaxial wafer grown by MBE or MOCVD process. The heterostructure has a high-mobility conduction channel formed by two-dimensional electron gas, which is an ideal material for wireless applications. The line width of our GaAs pHEMT process [...]
