Nanostructured Semiconductors. This thrust takes advantage of the low-temperature and gas-phase synthesis of our laser-aerosol methods to produce zinc oxide (ZnO) thin films and quantum dots that can be integrated into flexible electronics platformsand doped quantum confined structures of zinc selenide (ZnSe) for mid-infrared laser applications. These nanostructured semiconductor materials are difficult to produce by other physical deposition methods (e.g., MBE, CVD, MOCVD) and chemical approaches (e.g., colloidal, sol-gel, self-assembly).
