DOI: 10.1021/acsphotonics.7b00516
Abstract: Due to structural imperfection and indium content fluctuation, carriers’ localization in an InGaN-based active layer can produce efficient luminescence and unusual thermodynamic behaviors. Spectral features associated with localization, such as the “S-shaped” shift of peak… read more here.

DOI: 10.1038/srep45082
Abstract: Based on carrier rate equation, a new model is proposed to explain the non-exponential nature of time-resolved photoluminescence (TRPL) decay curves in the polar InGaN/GaN multi-quantum-well structures. From the study of TRPL curves at different… read more here.

DOI: 10.1063/1.4977707
Abstract: Recent reports have suggested that the long decay times in time resolved photoluminescence (TRPL), often measured in Cu(In, Ga)Se2 absorbers, may be a result of detrapping from sub-bandgap defects. In this work, we show via… read more here.
