p-type conductivity in wide-band-gap BaCuQF (Q=S,Se)

Creator:

Yanagi, Hiroshi, Tate, Janet, Park, Sangmoon, Park, Cheol-Hee, and Keszler, Douglas A.

Abstract:

BaCuQF (Q=S,Se) materials, candidate transparent p-type conductors, were prepared by solid-state reaction, and their bulk electrical and optical properties were evaluated. The room-temperature Seebeck coefficient and electrical conductivity of undoped BaCuQF pellets were +56 μV/K and 0.088 S/cm, respectively, for the sulfide fluoride, and +32 μV/K and 0.061 S/cm, respectively,...

High mobility transparent thin-film transistors with amorphous zinc tin oxide channel layer

Creator:

Chiang, H. Q., Wager, J. F., Hoffman, R. L., Jeong, J., and Keszler, Douglas A.

Abstract:

Transparent thin-film transistors (TTFTs) with an amorphous zinc tin oxide channel layer formed via rf magnetron sputter deposition are demonstrated. Field-effect mobilities of 5–15 and 20–50 cm² V‾¹ s‾¹ are obtained for devices post-deposition annealed at 300 and 600 °C, respectively. TTFTs processed at 300 and 600 °C yield devices...
