  • Methodology for forming pnictide compositions suitable for use in microelectronic devices
    Patent number: 9034685
    Abstract: The present invention provides methods for making pnictide compositions, particularly photoactive and/or semiconductive pnictides. In many embodiments, these compositions are in the form of thin films grown on a wide range of suitable substrates to be incorporated into a wide range of microelectronic devices, including photovoltaic devices, photodetectors, light emitting diodes, betavoltaic devices, thermoelectric devices, transistors, other optoelectronic devices, and the like. As an overview, the present invention prepares these compositions from suitable source compounds in which a vapor flux is derived from a source compound in a first processing zone, the vapor flux is treated in a second processing zone distinct from the first processing zone, and then the treated vapor flux, optionally in combination with one or more other ingredients, is used to grow pnictide films on a suitable substrate.
