Fig. 2: SE spectra and the derived absorption coefficient.
From: Optoelectronic properties and ultrafast carrier dynamics of copper iodide thin films
The measured (black square) and the fitted (red line) SE spectra (Ψ and Δ in a and b, respectively) of the as-grown CuI thin film with the angle of incidence of 65°. c Absorption coefficient α of CuI thin film with different treatments. Inset: zoom of α in the low value region.
