Physical properties of commonly prepared InP layers grown by LPE technique and those grown from Dy treated melt are compared. The layers were examined by SEM, low temperature PL spectroscopy, C-V measurements and temperature dependent Hall effect. Structural, electrical and optical properties of InP layers exhibit a significant dependence on the presence of Dy and its concentration in the melt. When increasing the concentration of Dy the reversal of electrical conductivity occurs.
