A time-resolved photoluminescence study of the defect-induced bound excitons (DIBE) observed in the energy region 1504–1511 meV in high quality molecular-beam epitaxy grown GaAs has been performed. Our results support the model that these lines consist of two distinct recombination processes. Transient resonant excitation of these DIBE demonstrate that the lines i to s can be associated with acceptor – bound exciton transitions.

Time Resolved Photoluminescence

We comprehensively studied InGaN/GaN heterostructures grown by molecular beam epitaxy (MBE) using a variety of methods of optical spectroscopy, such as cathodoluminescence microscopy (CL), time-integrated and time-resolved photoluminescence. To correlate the fluctuations in emission wavelength with values for the optical amplification we performed gain measurements in edge-stripe geometry. The lateral homogeneity can be drastically improved using a template of GaN grown on the sapphire substrate by metal-organic vapor phase epitaxy (MOVPE). Gain values up to 62 cm−1 were found in samples with low indium fluctuations, which is comparable to values for high-quality InGaN/GaN heterostructures grown by MOVPE.
