Samenvatting
In III-V semiconductors incorporation of small amounts of nitrogen cause a relatively large bandgap reduction. The problem of InGaAsN is the decrease in luminescence with nitrogen content above 1 - 2%.We have grown a.o. In0.65Ga0.35As0.985N0.015 quantum wells. The as-grown samples show poor photoluminescence at 4K but after a high temperature anneal clear peaks are observed. In comparision to ternary layers of In0.65Ga0.35As, the bandgap has decreased by approximately 70 meV due to 1.4 % of nitrogen. A further increase in the nitrogen content could result in layers with a bandgap of 800 meV at room temperature (l = 1.55 mm).
