Thin film engineering for transparent thin film transistors
… oxide (ZnO) and Indium Gallium Zinc Oxide (IGZO) thin films are of interest as oxide semiconductors in thin film transistor (TFT) applications, due to visible light transparency, and low deposition temperature. There is particular interest in ZnO and IGZO based transparent TFT devices fabricated …

Thin Film Energy Devices
The rapid emergence of the Internet-of-Things (IoT) is driving the demand for chipbased self-powered sensors that require energy harvesters and energy storage devices, i.e. “thin film energy devices”, as key components. The first section of this thesis introduces the working principle of a new type …

Scalable Perovskite Thin-Film Photovoltaics
In recent years lead halide based thin-film perovskites have emerged as a promising direct bandgap semiconductor for light absorption and emission applications. This is in part due to their compositional tunability and potential alloying that allows their color to be tuned from the near-IR through …

Pulsed Laser Deposition of Thin Film Heterostructures
<p> <p>Thin films of Strontium Ruthenate have been grown on Strontium Titanate and Lanthanum Aluminate (100) substrates by pulsed laser deposition. X-ray diffraction results show that the films grown on the Strontium Titanate are amorphous and polycrystalline on the Lanthanum Aluminate. Resistances …
