Thin film engineering for transparent thin film transistors
… techniques, particularly where alternatives to high temperature thermal treatments can be utilised in combination with low temperature substrates. This thesis presents the results of a series of experimental studies as an investigation into photonic (excimer laser) processing of low temperature …

Characterisation and optimisation of alternating current thin film electroluminescent displays
… for ZnS:Mn thin films deposited by RF magnetron sputtering has been presented and compared to KrF laser annealing (248nm wavelength). Additionally the use of KrF laser annealing on a new deposition method, High Target Utilisation Sputtering (HiTUS) is presented, with successful results obtained …

Low-dimensional electron transport and surface acoustic waves in GaAs and ZnO heterostructures
… GaAs, on a GaAs/AlGaAs heterostructure using high-target-utilisation sputtering (an Al2O3 buffer layer is deposited to protect the 2DEG during sputtering). With the ZnO, the SAW amplitude is greatly improved to 100 meV and the RF power required for pumping electrons using a SAW is greatly …

Reducing Off-State Current in P-Type Metal Oxide Thin Film Transistors
… Film Transistors (TFTs) are fabricated using High Target Utilisation Sputtering (HiTUS). In previous work, it was shown that the high off-current associated with Cu<sub>2</sub>O TFTs may be attributed to an atypical minority-carrier electron current leakage in the off-state. This gives a focus …

Bipolar metal oxide thin film diodes
… switch with larger current capability and higher frequency operation will prove to be beneficial. The growth of the Internet of Things (IoT) also results in increasing demand for transparent and conformable electronics, which requires materials that are highly uniform in electrical …
