Ultrafast μeV-Precision Bandgap Engineering in Low-Dimensional Topological Insulators
Peng Tan, Yuantao Chen, Yuqi Zhang +14
Precise and ultrafast control of electronic band structures is a central challenge for advancing quantum functional materials and devices. Conventional approaches--such as chemical…
Ultrafast symmetry modulation and induced magnetic excitation in the Kagome metal RbV3Sb5
Mengxue Guan, Xiaodong Zhou, Jingyi Duan +8
Light-matter interaction in frustrated Kagome metals enables access to hidden quantum states, yet the microscopic origin of symmetry breaking under ultrafast excitation remains elu…
Topological surface states in γ-PtBi evidenced by scanning tunneling microscopy
Yunkai Guo, Jingming Yan, Wen-Han Dong +11
For the application of topological materials, the specific location of their topological surface states with respect to the Fermi level are important. γ-PtBi2 has been demonstrated…
Shear-resistant topology in quasi one-dimensional van der Waals material BiBr
Jonathan K. Hofmann, Hoyeon Jeon, Saban M. Hus +10
BiBr is a prototypical quasi one-dimensional (1D) material in which covalently bonded bismuth bromide chains are arranged in parallel, side-by-side and layer-by-layer, with…
