Polarization-dependent ARPES studies on Cr_xNbS₂(x=0 and 1/3)

抄録

The electronic structure of 2H-Cr_x_NbS_2_(x=0,1/3) and the presence of circular dichroism in k-space has been studied by high resolution angle resolved photoemission spectroscopy at the BL-9B of Hiroshima Synchrotron Radiation Center (HSRC). The Fermi surface contours of 2H-Cr_x_NbS_2_(x=0,1/3) reveal a rounded hexagonal Fermi surface sheet centered at Γ point and a second approximately triangular sheet centered at K point and show the clear circular dichroism by changing the polarization of incident light.
