A semiconductor window which is transparent to light in the infrared range and which has good electrical conductivity is formed of a substrate material having a semiconductor coating having a dopant included therein. The coating is diffused, grown or deposited on one surface of the substrate and is controlled to obtain both low electrical resistivity and high infrared transmissivity. The coating can be formed of the same material as the substrate or can be a different material. Windows having particular thermal properties are formed utilizing zinc selenide and zinc sulfide as the substrate.

A conductive window transparent to infrared radiation comprising a substrate made of material selected from the group consisting of zinc sulfide, zinc selenide, sapphire, spinel and aluminum oxy nitride, said substrate being made to be transparent to infrared radiation, a thin coating of semiconductor material deposited on the surface of said substrate in a manner to be transparent to infrared radiation, a dopant contained in said semiconductor coating said dopant being selected to thereby form with said coating a semiconductor having significant carrier concentration of donors or acceptors, said dopant thereby causing said coating to exhibit conductivity with a sheet resistance of less than about 30 ohms per square, and the thickness of the semiconductor coating and the concentration of the dopant being adjusted to cause said coating to remain substantially transparent while exhibiting said conductivity.
