A p- or n-conductive semiconductor material comprises a compound of the general formula (I) <?in-line-formulae description="In-line Formulae" end="lead"?>Pb1-(x1+x2+ . . . +xn)A1x1A2x2 . . . AnxnTe1+z (I)<?in-line-formulae description="In-line Formulae" end="tail"?> where: in each case independently n is the number of chemical elements different from Pb and Te 1 ppm<=x1 . . . xn<=0.05 -0.05<=z<=0.05 and n>=2 A1 . . . An are different from one another and are selected from the group of the elements Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba, Al, Ga, In, Tl, Si, Ge, Sn, As, Sb, Bi, S, Se, Br, I, Sc, Y, La, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Hg, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu or n=1 A1 is selected from Ti, Zr, Ag, Hf, Cu, Gr, Nb, Ta.
