2. The Role of Interfacial Microstructure of Perovskite Thin FIlms - A High Resolution and In Situ Study
Sammanfattning : Perovskite based materials have recently shown to have many unique properties that make them suitable for future electronic devices. In this thesis, the role of the interfacial microstructure on the properties of perovskite thin film heterostructures has been investigated. LÄS MER
3. 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
4. Characterization of (Ba,Sr)TiO3 thin films for multiplier applications
Sammanfattning : (Ba,Sr)TiO3 (BSTO) and SrTiO3 (STO) parallel plate ferroelectric varactors are investigated for microwave multiplier applications.STO and BSTO exhibit low losses, high permittivity and largetunability of both permittivity and losses. All films are deposited using Pulsed Laser Deposition, magnetron sputtering and E-beam evaporation. LÄS MER
