Dielectric relaxation in As10Se90 amorphous film near the glass transition temperature

The quasi-static capacitance of As
₁₀
Se
₉₀
amorphous film was studied in cycles of heating and cooling near the glass transition temperature T
_g
=343 K. Features in the capacitance behavior such as the non-exponential relaxation and non-Arrhenius form of time relaxations in dependence on temperature are revealed. It was accepted, that the capacitance measurements allow finding the glass transition in thin amorphous film of As

₉₀
which is accompanied by freezing of some charged molecular dipoles.
