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

Precise Management of n‐Value Distribution at the 2D/3D Interface Enabling Efficient Wide‐Bandgap Perovskite Solar Cells

Advanced Science, EarlyView.
This study elucidates the phase transition pathway of surface‐engineered perovskite films. During spin‐coating, n = 1 2D perovskite dominantly forms, while subsequent annealing drives OA+ release and induces conversion to higher n‐value 2D phases.

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.

Delicate Management of Alkaline‐Substrate‐Induced Interfacial Reactions Enables High‐Efficiency and Stable Deep‐Red CsPbI3 Perovskite Light‐Emitting Diodes

Advanced Science, EarlyView.
We develop a magnesium‐doping strategy to delicately modulate the alkaline substrate‐induced reactions, ensuring high‐quality CsPbI3 perovskite emissive layers with substantially improved stability. The resultant deep‐red LEDs demonstrate a high peak external quantum efficiency of 23.62% and an exceptional half‐lifetime stability of 376 h at 20 mA cm−2,

Suppressing Morphological and Energetic Disorder in Copper Antimony Sulfide‐based Hole‐Transporting Materials via Ligand–Precursor Engineering for Efficient and Stable Perovskite Solar Cells

Advanced Science, EarlyView.
Sulfur‐precursor and ligand engineering regulate the nucleation, morphology, and energetic disorder of CuSbS2 nanocrystals for dopant‐free inorganic hole‐transport layers in perovskite solar cells. Thiourea‐assisted synthesis combined with optimized OAm/OAc coordination suppresses excessive anisotropic growth, enabling mixed plate‐like/quasi‐spherical ...
