An exotic metal-insulator transition in a surface-doped transition metal dichalcogenide
Metal-insulator transition (MIT) driven by many-body interactions is an important phenomenon in condensed matter physics. Exotic phases always emerge around the metal-insulator transition points where quantum fluctuations arise from a competition among spin, charge, orbital, and...

Toward a more comprehensive understanding of aridity changes over global drylands
Global drylands are experiencing faster-than-average warming and are also among the most vulnerable regions to climate change. Meteorological metrics all point to an emerging trend of increased surface aridity, raising concerns of land desertification and degradation. However, re...

Progress in fused-ring electron acceptors made by PKU Zhan Xiaowei’s group
During 1995-2015, fullerene derivatives had been the dominating electron acceptors in organic solar cells (OSCs) owing to their performance superior to other acceptors. However, the drawbacks of fullerenes, such as weak visible absorption, limited tunability of electronic propert...
