[23p-B203-8] Polarization-Dependent Optical Response in Dirac Semimetal PtSe2
Keywords:layered materials, Dirac semimetal, semiconductor
PtSe2, a transition metal dichalcogenide (TMDC), changes from a Dirac semimetal to a semiconductor as it is exfoliated from bulk to monolayer. While the polarization-dependent optical response to Dirac semimetals and thin film TMDCs has attracted much attention, little is known about PtSe2. In this presentation, we will report the results of helicity-resolved Raman spectroscopy of an exfoliated thin PtSe2 film onto a Si/SiO2 substrate.
