Abstract:
Conductivity inversion in thin $n$-InSe films under intense pulsed laser irradiation was obser. A $p$–$n$ structure based on indium selenide formed between irradiated and nonirradiated regions of a thin-film sample. It was confirmed by EDAX analysis that the composition of the sample remained the same after irradiation. The conductivity inversion is attributed to a change in the dynamics of lattice defects under heating.
