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…
Bandgap Lowering in Mixed Alloys of Cs2Ag(SbxBi1-x)Br6 Double Perovskite Thin Films
Zewei Li, Sean Kavanagh, Mari Napari +10
Halide double perovskites have gained significant attention, owing to their composition of low-toxicity elements, stability in air and long charge-carrier lifetimes. However, most…
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…
Transition-Edge Sensors for Particle Induced X-ray Emission Measurements
M. R. J. Palosaari, K. M. Kinnunen, J. Julin +10
In this paper we present a new measurement setup, where a transitionedge sensor detector array is used to detect X-rays in particle induced X-ray emission measurements with a 2 MeV…
