Dilute nitride InAsN epitaxial layers were produced using both liquid phase and molecular beam epitaxial growth techniques. The spectral features in the photoluminescence of samples containing up to 1% N with emission energies in the mid-infrared spectral region are described and compared. The emission intensities of both LPE and MBE grown materials were found to be comparable. Increasing the N content...
We review here our work on the growth of dilute GaAsN, GaSbN and InAsN epitaxial layers using a novel liquid phase epitaxy technique, first developed by us. The growth melt for these materials were prepared by using either polycrystalline GaN or InN powder as the source of nitrogen for Ga-based or In-based compounds, respectively. The nitrogen content in the grown materials was obtained through various...
Dilute GaAsN layers are grown by liquid phase epitaxy (LPE) technique, using polycrystalline GaN as the source of nitrogen. A band gap lowering of 100 meV is obtained from low temperature photoluminescence (PL) measurements which correspond to a little more than 0.5% nitrogen in the layer. Using 10 K photocapacitance measurements, a 0.7 eV electron trap is detected in the material which is assigned...
