Ultrathin PbI<sub>2</sub> single crystals for high sensitivity flexible photodetectors can be directly grown by virtue of their layered crystal structure.
Using lattice matched ZnO substrates, wurtzite single crystalline Mg0.49Zn0.51O films were obtained by reactive magnetron cosputtering method, and the heterostructures of MgZnO/ZnO fabricated into metal-semiconductor-metal solar-blind photodetectors (SBPDs). Calculated experimental results demonstrate that response substrate can be suppressed adopting a thick MgZnO epilayer. The SBPD with 2 μm epilayer shows peak responsivity 304 mA/W at 260 nm under 10 V bias, which is comparable to highest...

ZnO:Ga (GZO) materials with high thermal stability and carrier mobility are essential for the development of transparent conductive electrodes (TCE). Theoretically, only substitution doping Ga could result in main donor very stability. For achieving this goal, we adopted a hydrothermal method to acquire GZO single crystals, based on fact that can possibly provide an approximate thermodynamic equilibrium growth environment grow perfect Zn. A centimetre-sized crystal dosage amount 0.053 wt%...
Abstract High quality ZnO nanowires arrays were homoepitaxial grown on Ga-doped single crystal (GZOSC), which have the advantages of high conductivity, carrier mobility and thermal stability. When it was employed as a photoanode in DSSCs, cell exhibited 1.44% power-conversion efficiency under illumination one sun (AM 1.5G). The performance is superior to our nanowires/FTO based DSSCs same condition. This enhanced mainly attributed perfect interface between GZOSC substrate that contributes...

(Sp)-(+)-Spiniferin-1 and (Rp)-(−)-spiniferin-1, a pair of unusual marine natural products with planar chirality, were firstly synthesized via polyfluoroalkanosulfonyl fluoride induced homoallylic carbocation rearrangement reaction.
