Terahertz Spectroscopy of Amorphous WSe(2) and MoSe(2) Thin Films

Time domain spectroscopy is used to determine the THz electromagnetic response of amorphous transition metal dichalcogenides WSe(2) and MoSe(2) in thin-film form. The dielectric function is obtained using a rigorous transmission model to account for the large etalon effect. The Drude–Smith model is...

description Time domain spectroscopy is used to determine the THz electromagnetic response of amorphous transition metal dichalcogenides WSe(2) and MoSe(2) in thin-film form. The dielectric function is obtained using a rigorous transmission model to account for the large etalon effect. The Drude–Smith model is applied to retrieve the dielectric function, and from there, the sample conductivity.
