Optical signatures of phase transitions and structural modulation in elemental tellurium under pressure
Diego Rodriguez, Alexander A. Tsirlin, Tobias Biesner +5
A room-temperature infrared spectroscopy study of elemental tellurium at pressures up to 8.44 GPa in the energy range 0.015-2 eV is reported. Optical signatures of the high-pressur…

Two linear regimes in optical conductivity of a Type-I Weyl semimetal: the case of elemental tellurium
Diego Rodriguez, Alexander A. Tsirlin, Tobias Biesner +5
Employing high-pressure infrared spectroscopy we unveil the Weyl semimetal phase of elemental Te and its topological properties. The linear frequency dependence of the optical cond…
