Layered transition metal dichalcogenides (TMDs) are a diverse group of materials whose
properties vary from semiconducting to metallic with a variety of many body phenomena …

Noble‐metal chalcogenides, dichalcogenides, and phosphochalcogenides are an emerging
class of two‐dimensional materials. Quantum confinement (number of layers) and defect …

Over the past decade, topological materials—in which the topology of electron bands in the
bulk material leads to robust, unconventional surface states and electromagnetism—have …

Topological semimetals have recently attracted extensive research interests as host
materials to condensed matter physics counterparts of Dirac and Weyl fermions originally …

Recently, a new “type-II” Weyl fermion, which exhibits exotic phenomena, such as an angle-
dependent chiral anomaly, was discovered in a new phase of matter where electron and …

While a monolayer PtSe 2 film is a semiconductor with interesting spin structure, bulk PtSe 2
crystal has been predicted to be a topological Dirac semimetal that can host a new type of …

A Dirac fermion in a topological Dirac semimetal is a quadruple-degenerate quasiparticle
state with a relativistic linear dispersion. Breaking either time-reversal or inversion symmetry …

We report on a systematic study of type-II Dirac fermions in a layered crystal of PdT e 2. De
Haas–van Alphen oscillations show a small Fermi-surface pocket with a cross section of …

Ionic liquids provide versatile pathways for controlling the structures and properties of
quantum materials. Previous studies have reported electrostatic gating of nanometer-thick …

Transition-metal dichalcogenides (TMDs) are renowned for their rich and varied bulk
properties, while their single-layer variants have become one of the most prominent …
