High purity InP epitaxial layers were grown by LPE from the melt conataining, besides essential components, also rare-earth elements admixture. The layers were examined by SEM, low temperature PL spectroscopy, C-V measurements and temperature dependent Hall effect. The behaviour and the impact of Pr and Nd were compared. The concentration of shallow impurities was reduced by up to three orders of magnitude. PL spectra were markedly narrowed and fine spectral features were resolved.
