Role of Chalcogen-p States in the Optical Response of Bulk PtSe2 and PtTe2
Ji Eun Lee, R. Mathew Roy, Premakumar Yanda +3
The type-II Dirac semimetals PtSe and PtTe are isostructural and isovalent layered compounds but exhibit distinct electronic properties. We measure the in-plane infrared re…

Unconventional anisotropic charge dynamics in bulk -TaS induced by interlayer dimerization
Achyut Tiwari, Maxim Wenzel, Renjith Mathew Roy +3
The commensurate charge-density-wave phase of the prototypical transition metal dichalcogenide -TaS is investigated by temperature- and polarization-dependent infrared spec…
