Dielectric function of amorphous Selenium

Data available

This dataset contains the dielectric function of amorphous selenium, measured on a thin film deposited by chemical transport by spectroscopic ellipsometry. The fitting of the ellipsometric data was performed using a double Tauc-Lorentz oscillator.

Structure of the files

The data file consists of five columns. Each row corresponds to a distinct photon energy value.

The columns are ordered as follows:

1. Photon energy (eV)

2. Real part of the dielectric function, Re(ε)

3. Imaginary part of the dielectric function, Im(ε)

4. Refractive index, n

5. Extinction coefficient, k
