Abstract
Fine quality catenated phosphorus thin films are produced in a high vacuum evaporator. Heated tungsten wire crackers are provided above the phosphorus boat and below the substrates. Amorphous pure phosphorus shiny red films have been deposited on glass, metallized glass and GaP and exhibit an optical edge at 2.0 eV. Films of KP.sub.x where x is equal to 15 or greater than 15 are produced by utilizing a second baffled boat source containing the potassium graphite intercalate, KC.sub.8. Addition of a nickel evaporation source provides nickel-doped polyphosphide films.
