A method of surface potential determination in semiconductors by means of the transverse acoustoelectric effect is described. The results of theoreti­cal analysis of the transverse acoustoelectric voltage versus surface potential and different surface electrical parameters in indium phosphate single crys­tals are presented. The experimental results of the surface potential inves­tigations have been obtained after various surface treatments in InP(110) and InP(100) crystals. A strong influence of the chemical and mechanical surface treatments upon the surface potential values has been observed from the measurements. The surface InP(110) was more sensitive to different sur­face treatments. The changes of the surface potential values were about two times greater for InP(110) than for InP(100) samples. The surface potentials after surface treatments obtained by the acoustics method were of the range -0.08 [V] to -0.22 [V].
