Bulk and surface electronic states in the dosed semimetallic HfTe
Zakariae El Youbi, Sung Won Jung, Saumya Mukherjee +8
The dosing of layered materials with alkali metals has become a commonly used strategy in ARPES experiments. However, precisely what occurs under such conditions, both structurally…
Fermi-crossing Type-II Dirac fermions and topological surface states in NiTe2
Saumya Mukherjee, Sung Won Jung, Sophie F. Weber +9
Transition-metal dichalcogenides (TMDs) offer an ideal platform to experimentally realize Dirac fermions. However, typically these exotic quasiparticles are located far away from t…
Universal Mechanism of Band-Gap Engineering in Transition-Metal Dichalcogenides
Mingu Kang, Beomyoung Kim, Sae Hee Ryu +7
Two-dimensional (2D) van-der-Waals semiconductors have emerged as a class of materials with promising device characteristics owing to the intrinsic bandgap. For realistic applicati…
Two-Dimensional Dirac Fermions Protected by Space-Time Inversion Symmetry in Black Phosphorus
Jimin Kim, Seung Su Baik, Sung Won Jung +5
We report the realization of novel symmetry-protected Dirac fermions in a surface-doped two-dimensional (2D) semiconductor, black phosphorus. The widely tunable band gap of black p…
