Cathodoluminescence quantum yield of CdSe epilayers grown in a quasi-closed system

We have assessed the influence of growth process conditions and electron beam excitation density on the external quantum yield of cathodoluminescence in n -CdSe epilayers grown in a quasi-closed system. The highest external quantum yield (2.2% at a temperature of 78 K) has been offered by n -CdSe ep...

Zusammenfassung:We have assessed the influence of growth process conditions and electron beam excitation density on the external quantum yield of cathodoluminescence in n -CdSe epilayers grown in a quasi-closed system. The highest external quantum yield (2.2% at a temperature of 78 K) has been offered by n -CdSe epilayers grown under near-equilibrium high-temperature deposition conditions.
