Specific features of some Rare Earth Elements (REE= Nd, Ho or Tb) are exploited to improve structural, optical and electrical properties of InP-based layer compounds for applications in ionizing radiation detector structures. InP layers were grown by Liquid Phase Epitaxy on (100)-oriented single crystal InP substrates with individual REE addition to the melt. The density of structural defects was reduced by more than a half order of magnitude, free carrier concentration was reduced effectively by up to four orders of magnitude, photoluminescence peaks were substantially narrowed and fine spectral features were resolved.
