The test-QD in-situ annealing method could surmount the critical nucleation condition of InAs/GaAs single quantum dots (SQDs) to raise the growth repeatability. Here, through many growth tests on rotating substrates, we develop a proper In deposition amount (θ) for SQD growth, according to the measured critical θ for [...]
Impact of GaN buffer growth conditions on photoluminescence and X-ray diffraction characteristics of MOVPE grown bulk GaN
Properties of metalorganic vapor phase epitaxy (MOVPE) grown GaN bulk layers with varying GaN buffer growth conditions are characterized by low-temperature (6K) photoluminescence (LT-PL) and X-ray diffraction (XRD). [...]
AlGaInP is used in manufacture of light-emitting diodes of high-brightness red, orange, green, and yellow color, to form the heterostructure emitting light. It is also used to make diode lasers.
AlGaInP layer is often grown by heteroepitaxy on gallium arsenide or gallium phosphide in order to form a quantum well structure.
