Sažetak
Temperature dependence of the free hole concentration is studied in Ga:Mg samples grown by MOCVD technique. Relevant parameters are determined, like the ionization energy, the degree of compensation and the concentrations of donors and acceptors. Methods for the determination of these parameters are discussed. It is shown that reliable data on the ionization energy and the compensation can be obtained while determination of the concentrations of donors and acceptors is much less reliable. The value of the degeneracy factor of the acceptor level is explored since it influences the degree of compensation and the free carrier concentration. Occurrence of the maximum in free carrier concentration with the increase of Mg-dopand concentration in MOCVD samples is examined. It is shown that multicharged donors are needed for explanation, among which the complex formed by magnesium atom and the nitrogen vacancy (Mg_Ga V_N) is the plausible candidate.
