Giant exciton effects and magneto-excitonic coupling in V4S9X4 2D magnetic semiconductors
Yingjie Wei, Fan Zhang, Ying Zhao +4
Room-temperature spin-optoelectronic devices require a combination of robust ferromagnetism and giant exciton binding, a pairing mutually exclusive in conventional semiconductors d…
Efficient Screening of Organic Singlet Fission Molecules Using Graph Neural Networks
Li Fu, Longfei Lv, Fan Zhang +3
Singlet fission (SF) provides a promising strategy for surpassing the Shockley-Queisser limit in photovoltaics. However, the identification of efficient SF materials is hindered by…
Efficiently charting the space of mixed vacancy-ordered perovskites by machine-learning encoded atomic-site information
Fan Zhang, Li Fu, Weiwei Gao +2
Vacancy-ordered double perovskites (VODPs) are promising alternatives to three-dimensional lead halide perovskites for optoelectronic and photovoltaic applications. Mixing these ma…
Cluster Sliding Ferroelectricity in Trilayer Quasi-Hexagonal C
Xuefei Wang, Yanhan Ren, Shi Qiu +5
Electric polarization typically originates from non-centrosymmetric charge distributions in compounds. In elemental crystalline materials, chemical bonds between atoms of the same…
