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.

Photoelectric‐Coupled Ferroelectric Heterojunctions for Ultrahigh NO2 Sensing With Polarization‐Memory‐Assisted Interfacial Modulation

Advanced Science, EarlyView.
This study demonstrates a Bi2WO6/SrBi2Ta2O9 heterojunction where light‐driven ferroelectric polarization reversal couples with persistent photoconductivity, enabling exclusive NO2 selective room‐temperature sensing. The device achieves a two‐order‐of‐magnitude sensitivity enhancement over an unpolarized device, a sub‐ppb detection limit, and robust ...

Sulfonated Bathocuproine Derivatives as Chemically Bonded Buried‐Interface Engineers for n–i–p Perovskite Solar Cells

Advanced Science, EarlyView.
A BCP‐derived buried‐interface strategy establishes Na‐BCS as a chemically bonded molecular bridge. By combining sulfonate anchoring to SnO2 with preserved BCP–Pb2+ coordination, Na‐BCS simultaneously passivates oxide‐ and perovskite‐side defects, suppresses non‐radiative recombination, and delivers a surface recombination velocity of 8.6 cm s−1, a ...
