Summary of Experience
Synthesized and examined a novel metal-insulator composite for superconducting interactions; Synthesized high quality Nb3Ge thin films and measured effect of radiation damage on the resistivity and superconducting transition temperature; Fabricated hydrogenated amorphous silicon alloy films. Achieved record solar cell efficiency of greater than 7%. Successfully fabricated and directed efforts to fabricate thin superconducting films of YBa2Cu3O7 and Tl2CaBa2Cu2Ox.
