Abstract:
Luminescence properties of epilayers of Ga$_{1-x}$In$_{x}$As$_{y}$P$_{1-y}$ (GaInAsP) solid solutions with graded content of Group V elements ($\Delta y$ up to 0.08 over a total thickness of about 1 $\mu$m) were studied at 77 and 300 K. The photoluminescence (PL) spectra of GaInAsP epilayers with large $\Delta y$ values were broadened. The GaInAsP epilayers of low crystalline perfection exhibited either no PL emission or showed PL spectra characteristic of transitions involving impurity energy levels.
Keywords:
photoluminescence, solid solutions, heterostructures, photovoltaic converters.
