Sensitive infrared surface photovoltage in quasi-equilibrium in a layered semiconductor at low-intensity low-temperature condition
Qiang Wan, Keming Zhao, Guohao Dong +10
Benefit to layer-dependent bandgap, van der Waals materials with surface photovoltaic effect (SPV) enable photodetection over a tunable wavelength range with low power consumption.…
Angle-resolved photoemission spectroscopy of superconducting (La,Pr)3Ni2O7/SrLaAlO4 heterostructures
Peng Li, Guangdi Zhou, Wei Lv +19
Ruddlesden-Popper bilayer nickelate thin film superconductors discovered under ambient pressure enable vast possibilities for investigating electronic structures of the superconduc…
Discovery of a metallic room-temperature d-wave altermagnet KV2Se2O
Bei Jiang, Mingzhe Hu, Jianli Bai +19
Beyond conventional ferromagnetism and antiferromagnetism, altermagnetism is a recently discovered unconventional magnetic phase characterized by time-reversal symmetry breaking an…
Evidence for an Excitonic Insulator State in TaPdTe
Jierui Huang, Bei Jiang, Jingyu Yao +30
The excitonic insulator (EI) is an exotic ground state of narrow-gap semiconductors and semimetals arising from spontaneous condensation of electron-hole pairs bound by attractive…
