사파이어(Al2O3) 템플릿 위의 GaN 박막

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 Type-II 초격자의 성장

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 [...]

평면 또는 PSS 사파이어 기판의 GaN LED 구조 에피택시

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 [...]

발광체용으로 성장한 GaAs 기반 Epi 구조 MOCVD

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.

GaN 기판의 GaN 박막 에피택시에서 Mg의 P형 도핑

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 [...]

InGaN / GaN 다중양자 우물의 나노스케일 V형 피트

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. [...]
