Growth and characterization of the p-type semiconductors SnS and BiCuOSe

Creator:

Francis, Jason

Abstract:

BiCuOSe and SnS are layered, moderate band gap (ε[subscript G] ≈ 1 eV) semiconductors that exhibit intrinsic p type conductivity. Doping of BiCuOSe with Ca results in a slight expansion of the lattice and an increase of the hole concentration from 10¹⁸ cm⁻³ to greater than 10²⁰ cm⁻³. The large...

Examining the Environmental Behavior and Treatment Efficacy of Titanium Dioxide Nanomaterials in Complex Systems

Creator:

Deline, Alyssa R.

Abstract:

Metal oxide nanoparticles (MONPs) are manufactured at the greatest rate of any class of nanomaterial due to their wide variety of industrial, commercial, and environmental applications. The sustainable use of MONPs requires a balance of careful consideration of their potential negative environmental impacts with the effective exploitation of their unique...

Substitution Effects on the Structure and Electronic Behavior of Ternary Precious Metal Oxides

Creator:

Flynn, Joshua

Abstract:

Due to the high cost of precursor materials, complex oxides of 4d and 5d transition metals are under-studied compared to their 3d counterparts. Recent studies have shown that oxides containing heavier transition metals can exhibit exotic electronic states due to presence of strong spin-orbit coupling. The goal of this dissertation...
