p-Type conductivity in wide-band-gap BaCuQF (Q=S, Se)
TLDR
In this article, 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.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, for the selenide fluoride. The conductivity was greatly enhanced by the substitution of several percent of K for Ba; the highest conductivities were 82 S/cm for Ba0.9K0.1CuSF and 43 S/cm for Ba0.9K0.1SeF. The band gaps for Q=S and Q=Se were measured to be 3.2 and 3.0 eV, respectively. Undoped BaCuSF exhibits strong red luminescence near 630 nm under ultraviolet excitation.read more

Room-temperature synthesized copper iodide thin film as degenerate p-type transparent conductor with a boosted figure of merit.
TL;DR: A degenerate p-type conduction of cuprous iodide (CuI) thin films is achieved at the iodine-rich growth condition, allowing for the record high room-temperature conductivity and transparency, which boosts the figure of merit of a p- type TC from ∼200 to ∼17,000 MΩ−1.

New contributions to the optics of intensely light-scattering materials.
TL;DR: In this paper, the Gurevic and Judd formulas were derived from the Kubelka-Munk differential equations, and they are exact under the same conditions as in this paper, that is, when the material is perfectly dull and when the light, is perfectly diffused or if it is parallel and hits the specimen under an angle of 60° from normal.

P-type electrical conduction in transparent thin films of CuAlO2
TL;DR: In this paper, the authors describe a strategy for identifying oxide materials that should combine p-type conductivity with good optical transparency, and illustrate the potential of this approach by reporting the properties of thin films of CuAlO2, a transparent oxide having room-temperature p- type conductivity up to 1'S'cm−1.
