Nanoscale probing of image-potential states and electron transfer doping in borophene polymorphs
Xiaolong Liu, Luqing Wang, Boris I. Yakobson +1
Using field-emission resonance spectroscopy with an ultrahigh vacuum scanning tunneling microscope, we reveal Stark-shifted image-potential states of the v_1/6 and v_1/5 borophene…
Severe Dirac Mass Gap Suppression in Sb_2Te_3-based Quantum Anomalous Hall Materials
Yi Xue Chong, Xiaolong Liu, Rahul Sharma +5
Quantum anomalous Hall (QAH) effect appears in ferromagnetic topological insulators (FMTI) when a Dirac mass gap opens in the spectrum of the topological surface states (SS). Unacc…
Discovery of a Cooper-Pair Density Wave State in a Transition-Metal Dichalcogenide
Xiaolong Liu, Yi Xue Chong, Rahul Sharma +1
Pair density wave (PDW) states are defined by a spatially modulating superconductive order-parameter. To search for such states in transition metal dichalcogenides (TMD) we use hig…
