Interweaving Polar Charge Orders in a Layered Metallic Super-atomic Crystal
Shuya Xing, Linlu Wu, Zilu Wang +15
Electronic properties of super-atomic crystals have not been sufficiently explored due to the versatility of their building units; moreover, their inter-unit couplings are even poo…
Intrinsic magnetic topological insulator phases in the Sb doped MnBi2Te4 bulks and thin flakes
Bo Chen, Fucong Fei, Dongqin Zhang +23
Magnetic topological insulators (MTIs) offer a combination of topologically nontrivial characteristics and magnetic order and show promise in terms of potentially interesting physi…
Low spin-polarization in the heavy metal\ferromagnet structures detected through the domain wall motion by synchronized magnetic field and current
Xueying Zhang, Nicolas Vernier, Laurent Vila +9
CoFeB is a very soft material, in which Domain Wall (DW) can be moved easily under a weak magnetic field. However, it is very difficult to move DWs in Ta\CoFeB\MgO nanowires with i…
Experimental observation of bulk nodal lines and electronic surface states in ZrB
Rui Lou, Pengjie Guo, Man Li +14
Topological nodal-line semimetals are characterized by the line-contact bulk band crossings and the topological surface states. Breaking certain protecting symmetry turns this syst…
Towards Intrinsic Charge Transport in Monolayer Molybdenum Disulfide by Defect and Interface Engineering
Zhihao Yu, Yiming Pan, Yuting Shen +12
Molybdenum disulfide is considered as one of the most promising two-dimensional semiconductors for electronic and optoelectronic device applications. So far, the charge transport i…
Two-dimensional Quasi-Freestanding Molecular Crystals for High-Performance Organic Field-Effect Transistors
Daowei He, Yuhan Zhang, Qisheng Wu +18
Two-dimensional atomic crystals are extensively studied in recent years due to their exciting physics and device applications. However, a molecular counterpart, with scalable proce…
Strong Photoluminescence Enhancement of MoS2 through Defect Engineering and Oxygen Bonding
Haiyan Nan, Zilu Wang, Wenhui Wang +9
We report on a strong photoluminescence (PL) enhancement of monolayer MoS2 through defect engineering and oxygen bonding. Micro- PL and Raman images clearly reveal that the PL enha…
Hopping Transport through Defect-induced Localized States in Molybdenum Disulfide
Hao Qiu, Tao Xu, Zilu Wang +12
Molybdenum disulfide is a novel two-dimensional semiconductor with potential applications in electronic and optoelectronic devices. However, the nature of charge transport in back-…
