Pulsed laser deposition and thin film properties of p-type BaCuSF, BaCuSeF, BaCuTeF and n-type Zn₂In₂O[subscript 5] wide band-gap semiconductors

Creator:

Kykyneshi, Robert

Abstract:

Thin films of wide band-gap semiconductors are deposited by the pulsed laser deposition method. Optimal deposition parameters for the individual compounds are reported. A family of p-type BaCuQF (Q = S, Se, Te) ceramics with a layered crystalline structure is investigated for active and passive device applications. Epitaxial films of...

Abstract:

Bulk properties of CuSc₁₋ₓMgₓO₂, CuSc₁₋ₓMgₓO₂₊y, BaCu₂S₂, Bai₁₋ₓKCu₂S₂, BaCu₂Se₂ and Bai₁₋ₓKₓCu₂Se₂ are investigated supporting the search for highly conductive p-type thin films. Mg is an efficient dopant in CuScO₂ with conductivity up to l.5.10⁻² S/cm. Oxidation of CuScO₂:Mg leads to further increase in conductivity up to 0.5 S/cm. The amount of...
