The characterization of InP (>10mć) layers prepared by LPE with Pr, Dy or Tb (REE) addition in the melt is reported. The conductivity has been changed from n to p type when REE exceeded certain concentration limit (0.15 wt per cent for Pr, 0.05 wt per cent for Tb and 0.03 for Dy). Comparison of PL peaks of n- and p- type conductivity laeyrs with obtained electrical data lead to conclusion that the dominant acceptor impurity for the n- and p-n type crossover is Ge for Pr addition and Mn for Tb and Dy addition.
