Transparent thin film transistors of polycrystalline SnO2−x and epitaxial SnO2−x

AIP Advances, 2020
We report on transparent thin film field effect transistors (TFTs) based on polycrystalline SnO2−x and epitaxial SnO2−x. Polycrystalline SnO2−x TFTs of the top and the bottom gate geometries exhibited high mobility values of 145.7 cm2/V s and 160.0 cm2/V

Synthesis and Gas Sensing Properties of Single La-Doped SnO2 Nanobelts

Sensors, 2015
Single crystal SnO2 nanobelts (SnO2 NBs) and La-SnO2 nanobelts (La-SnO2 NBs) were synthesized by thermal evaporation. Both a single SnO2 NB sensor and a single La-SnO2 NB sensor were developed and their sensing properties were investigated.

Silver layer instability in a SnO2/Ag/SnO2 trilayer on silicon

Thin Solid Films, 2012
Abstract Trilayers of SnO2/Ag/SnO2 deposited on oxidized Si (100) substrates at room temperature become unstable after annealing at 100 °C and 200 °C, exhibiting five phenomena – formation of internal Ag hillocks, cracking of the top SnO2 layer above internal Ag hillocks, penetration of Ag/Ag grain boundaries by SnO2 leading to grain pinch-off ...

Patterning of Lead Halide Perovskite Device Stacks on CMOS Readout Using Selective Microfabrication Protocols

Advanced Materials, EarlyView.
We present a microfabrication and integration strategy for lead halide perovskite photodetectors on electronic readouts. Standard photolithography, aqueous processing, selective transparent electrode etching, and plasma‐assisted pixel isolation enable precise monolithic integration of patterned 400 × 400 perovskite microphotodetector arrays on a CMOS ...
