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...

Sumario: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.
