We report on the influence of rare earth (RE) elements (Pr, Er, and Dy) addition during vertical Bridgman low pressure synthesis on the properties of InP crystals. The temperature dependent Hall measurement and low-temperature photoluminescence (PL) spectroscopy were employed to study the changes in electrical and optical properties of the crystals. The observed changes are attributed to the gettering...
The influence of Yb and Yb2O3 addition on the properties of InP epitaxial layers is reported. We concentrated on the investigation of gettering and/or doping efficiency of Yb added in various forms. Layers prepared by Liquid Phase Epitaxy were examined by using SEM, SIMS, low temperature PL spectroscopy, C-V and temperature dependent Hall measurements. The efficient gettering was confirmed for both...
