The optical investigation of tungsten diphosphide (WP2), a type-II Weyl semimetal, reveals its exceptional topological and anisotropic electronic properties. Through resistivity and Fourier-transform infrared spectroscopy measurements, WP2 exhibit high conductivity and anisotropic transport...

This dissertation is devoted to the investigation of the optical properties of two topological insulators, Bismuth Selenide (Bi2Se3) and Antimony Telluride (Sb2Te3), by optical spectroscopy reflection measurements in a wide frequency range (500 – 40000 cm−1 ) and temperature (13 to 300 K) ....
