In-plane and out-of-plane optical response of the nodal-line semimetals ZrGeS and ZrGeSe

Polarization-dependent reflectivity measurements were carried out over a broad frequency range on single-crystalline ZrGeSe and ZrGeS compounds, which are closely related to the prototype nodal-line semimetal ZrSiS. These measurements revealed the strongly anisotropic character of both ZrGeSe and ZrGeS, with a reduced plasma frequency for the out-of-plane direction $E\parallel c$ as compared with the in-plane direction $E\parallel ab$.

Pressure-induced excitations in the out-of-plane optical response of the nodal-line semimetal ZrSiS

The anisotropic optical response of the layered, nodal-line semimetal ZrSiS was investigated for the first time by frequency-dependent reflectivity measurements for the polarization along and perpendicular to the layers. Under external pressure, two prominent excitations appear in the out-of-plane optical conductivity, which are discussed in the context of the recently proposed excitonic insulator phase in ZrSiS.
