1. Growth and Characterisation of Non-linear Ferroelectric Heterostructures
Sammanfattning : High dielectric constant or ferroelectric materials are needed for a range of devices, non-volatile ferroelectric computer memories, NVFRAMs, microwave devices utilising the non-linear polarisation as a function of electric field, or other microwave applications. High dielectric constant and low losses can be achieved in single crystals of ferroelectrics. LÄS MER

3. Upconversion Detection for Improved Nonlinear Mid-infrared Spectroscopy in Flames
Sammanfattning : This thesis deals with the addition of upconversion detection to non-linear mid-infrared laser spectroscopy techniques. The techniques investigated here are degenerate four wave mixing (DFWM) and infrared polarization spectroscopy (IRPS). LÄS MER
