Novel Methods For The Crystallization Of Thin Film Silicon, Shane Mcmahon
Legacy Theses & Dissertations (2009 - 2024)
Underpinning much of the technological innovation over the past few decades in the fields of sensors, lighting, displays, and energy conversion has been thin-film electronics. While many of the surfaces in our environment have curvature, silicon wafers do not. Flexible electronics attempt to overcome this fundamental limitation in form factor. Flexible thin-film transistors (TFTs) can be fabricated over large areas to provide switching and driving elements for displays and other devices. While printable organic semiconductors have made significant advances over the past few years, they cannot match the performance capability, electrical quality, temperature compatibility, or stability of silicon. For this …

Background: Silicon Photonics has been rapidly developing as a field. The primary reason for this is its lower operating costs and faster switching rates for use in big data centres. Instead of microns-wide copper lines to transmit signals, silicon photonic chips use waveguides, usually of silicon or silicon nitride. Photonic signals bypass the issues of resistive-capacitance lag (RC-lag) and resistive-heating encountered by copper lines. Additionally, a single waveguide may transmit multiple signals along different carrier wavelengths.
