Charge Density Waves in Electron-Doped Molybdenum Disulfide

Charge Density Waves in Electron-Doped Molybdenum Disulfide

We present the discovery of a charge density wave (CDW) ground state in heavily electron-doped molybdenum disulfide (MoS2). This is the first observation of a CDW in any d2 (column 6) transition metal dichalcogenide (TMD). The band structure of MoS2 is distinct from the d0 and d1 TMDs in which …
