Growth and photoluminescence studies of a-plane AlN/AlxGa1−xN quantum wells
Both a-plane and c-plane AlN/Al0.65Ga0.35N quantum wells QWs have been grown by metal organic chemical vapor deposition and their photoluminescence PL emission properties were studied and compared. It was found that the low temperature PL characteristics of a-plane QWs are primarily governed by the quantum size effect, whereas those of c-plane QWs are significantly affected by the polarization ...
متن کاملAlGaN/AlN multiple quantumwells grown by MOVPE on AlN templates using nitrogen as a carrier gas
AlxGa1 xN/AlN multiple quantum wells (MQWs) structures were grown by metalorganic vapour phase epitaxy (MOVPE) on pseudo AlN substrates using nitrogen as a carrier gas. Results of X-ray diffraction (XRD) and reciprocal space mapping (RSM) indicated no sign of strain relaxation in the quantum wells with respect to the AlN substrate. The MQW parameters such as thicknesses, growth rates and materi...
متن کاملIntersubband absorption properties of high Al content AlxGa1−xN/GaN multiple quantum wells grown with different interlayers by metal organic chemical vapor deposition
High Al content AlxGa1-xN/GaN multiple quantum well (MQW) films with different interlayers were grown by metal organic chemical vapor deposition. These MQWs were designed to achieve intersubband (ISB) absorption in the mid-infrared spectral range. We have considered two growth conditions, with AlGaN interlayer and GaN/AlN superlattice (SL) interlayer, both deposited on GaN-on-sapphire templates...
متن کاملStructural, morphological, and optical properties of AlGaN/GaN heterostructures with AlN buffer and interlayer
AlxGa1−xN/GaN x 0.3 heterostructures with and without a high-temperature HT AlN interlayer IL have been grown on sapphire Al2O3 substrates and AlN buffer/Al2O3 templates by metal organic chemical vapor deposition. The effects of an AlN buffer layer BL grown on an Al2O3 substrate and an AlN IL grown under the AlGaN ternary layer TL on structural, morphological, and optical properties of the hete...
متن کاملSimulation supported analysis of the effect of SiNx interlayers in AlGaN on the dislocation density reduction
In the last few years aluminium nitride (AlN) has attracted much attention due to its extremely large direct band gap of approximately 6.0 eV and its impressive chemical and thermal stability. Thus AlN and AlxGa1-xN ternary alloys are promising materials for high-power high temperature electronic applications and optoelectronic devices in UV range. For group-III nitride wafers are still not ava...
