Role of ALD Al2O3 surface passivation on the performance of p-type Cu2O thin film transistors
Mari Napari, Tahmida N. Huq, David J. Meeth +10
High-performance p-type oxide thin film transistors (TFTs) have great potential for many semiconductor applications. However, these devices typically suffer from low hole mobility…
Experimental evidence on photo-assisted O ion production from AlO cathode in cesium sputter negative ion source
O. Tarvainen, R. Kronholm, M. Laitinen +8
The production of negative ions in cesium sputter ion sources is generally considered to be a pure surface process. It has been recently proposed that ion pair production could exp…
Ti alloyed -GaO: route towards wide band gap engineering
A. Barthel, J. W. Roberts, M. Napari +6
The suitability of Ti as a band gap modifier for -GaO was investigated, taking advantage of the isostructural α-phases and high band gap difference between TiO a…
Printed high-mobility p-type buffer layers on perovskite photovoltaics for efficient semi-transparent devices
Robert A. Jagt, Tahmida N. Huq, Sam A. Hill +10
Perovskite solar cells (PSCs) with transparent electrodes can be integrated with existing solar panels in tandem configurations to increase the power conversion efficiency. A criti…
