Magnetism and Electrical Conduction in Lightly-Doped Single-Layer High- T c Cuprate La 2 CuO 4+ δ

The temperature dependences of magnetization and electrical resistivity as well as their magnetic field dependences have been examined in lightly-doped single-layer cuprate La 2 CuO 4+ δ [LCO, hole-doping level p(2δ) ≅ 0.03] single crystals, in comparison with those in the extrem...

Spatial Control of Spontaneous Orientation Polarization for Efficient Charge Separation in Organic Photovoltaics

ABSTRACT Spontaneous orientation polarization (SOP) offers a unique approach to generating internal electric fields in organic photovoltaics (OPVs). However, in conventional high‐performance OPVs based on bulk heterojunction architectures, the complex nanoscale morphology makes i...
