Petti L, Faber H, Muenzenrieder N, et al., 2015, Low-temperature spray-deposited indium oxide for flexible thin-film transistors and integrated circuits, Applied Physics Letters, Vol: 106, ISSN: 1077-3118
Indium oxide (In2O3) films were deposited by ultrasonic spray pyrolysis in ambient air and incorporated into bottom-gate coplanar and staggered thin-film transistors. As-fabricated devices exhibited electron-transporting characteristics with mobility values of 1 cm2V−1s−1 and 16 cm2V−1s−1 for coplanar and staggered architectures, respectively. Integration of In2O3 transistors enabled realization of unipolar inverters with high gain (5.3 V/V) and low-voltage operation. The low temperature deposition (≤250 °C) of In2O3 also allowed transistor fabrication on free-standing 50 μm-thick polyimide foils. The resulting flexible In2O3 transistors exhibit good characteristics and remain fully functional even when bent to tensile radii of 4 mm.
Labram JG, Lin Y-H, Zhao K, et al., 2015, Signatures of Quantized Energy States in Solution-Processed Ultrathin Layers of Metal-Oxide Semiconductors and Their Devices, Advanced Functional Materials, Vol: 25, Pages: 1727-1736, ISSN: 1616-3028
Physical phenomena such as energy quantization have to-date been overlooked in solution-processed inorganic semiconducting layers, owing to heterogeneity in layer thickness uniformity unlike some of their vacuum-deposited counterparts. Recent reports of the growth of uniform, ultrathin (<5 nm) metal-oxide semiconductors from solution, however, have potentially opened the door to such phenomena manifesting themselves. Here, a theoretical framework is developed for energy quantization in inorganic semiconductor layers with appreciable surface roughness, as compared to the mean layer thickness, and present experimental evidence of the existence of quantized energy states in spin-cast layers of zinc oxide (ZnO). As-grown ZnO layers are found to be remarkably continuous and uniform with controllable thicknesses in the range 2–24 nm and exhibit a characteristic widening of the energy bandgap with reducing thickness in agreement with theoretical predictions. Using sequentially spin-cast layers of ZnO as the bulk semiconductor and quantum well materials, and gallium oxide or organic self-assembled monolayers as the barrier materials, two terminal electronic devices are demonstrated, the current–voltage characteristics of which resemble closely those of double-barrier resonant-tunneling diodes. As-fabricated all-oxide/hybrid devices exhibit a characteristic negative-differential conductance region with peak-to-valley ratios in the range 2–7.

Lin YH, Zhao K, Li R, et al., 2015, Exploring low-dimensional charge transport phenomena in solution-processed metal oxide superlattice transistors, Pages: 1736-1739, ISSN: 1883-2490
© 2015 Proceedings of the International Display Workshops. All rights reserved. We report on metal oxide superlattice systems grown from solution and their use in high electron mobility transistors. On the basis of temperature-dependent electron transport measurements and carrier distribution evaluation, we argue that the enhanced performance arises from the presence of 2-dimensional electron gaslike systems formed at the oxide-oxide heterointerfaces.

Yaacobi-Gross N, Treat ND, Pattanasattayavong P, et al., 2014, High-Efficiency Organic Photovoltaic Cells Based on the Solution-Processable Hole Transporting Interlayer Copper Thiocyanate (CuSCN) as a Replacement for PEDOT:PSS, Advanced Energy Materials, Vol: 5, ISSN: 1614-6840
The use of copper thiocyanate (CuSCN) as a universal solution-processable and highly transparent hole-transporting layer in organic bulk-heterojunction photovoltaic cells is demonstrated. When CuSCN is employed as a replacement for the commonly used poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS), organic solar cells with maximum power conversion efficiency of 8%, are realized; this value is 1.27 times higher than that for optimized control cells based on PEDOT:PSS.
