A semiconducting material, consisting of an alloy composition of aluminium antimonide and gallium antimonide, contains (by weight): .Ga.0,93.-.33,5 per cent .Al.1,44.-.17,65 per cent .Sb.the remainder,.. the weight percentage of Ga plus 2,01 times the weight percentage of Al being equal to 36,4 to 3 significant figures. A particular composition described consists of: Ga 20,5 per cent; Al 7,9 per cent; Sb the remainder. The conductivity type of the material may be modified by adding zinc antimonide, cadmium antimonide, gallium telluride, gallium selenide or gallium sulphide up to a total of 0,01 atomic per cent.
