The effects of electron-beam (E-beam) irradiation on the formation of CuInSe$_2$ (CIS) thin films were investigated through a structural characterization of amorphous CIS (a-CIS) thin-films co-evaporated onto glass substrates. A-CIS thin-films were either heat-treated or subjected to E-beam irradiation. With the E-beam treatment, the crystallization temperature significantly decreased. This is probably due to the catalytic effect of the electrons reducing the activation energy and promoting the nucleation and growth of crystallite grains. The results imply that crystallization can be promoted by using an electron-mediated catalytic effect. The findings in this study open the way for low-temperature crystallization of CIS thin films.
