InP single crystal layers were grown by LPE on semi-insulating InP with various rare earth elements added to the melt. The layers were characterized by temperature dependent Hall measurements and by low temperature photo-luminescence spectroscopy. P-type InP grown with Tb and Yb admixture was studied. The dominant acceptor in the case of Tb was identified as Mn on the In site. In the case of Yb the dominant acceptor was identified as isoelectronic Yb in In site with strong electron-lattice interaction.
