Abstract

Semieonducting GaxTe~oo-x (17 -< x _< 25) glasses have been prepared by melt quenching method and thermal crystallization studies carried out using differential scanning calorimetry. On heating, virgin GaxTel0o-x glasses exhibit one glass transition and two crystallization reactions.The first crystallization reaction corresponds to the precipitation of hexagonal Te and the second one to the crystallization of the matrix into zinc blende Ga2Te3 phase. If GaxTeloo-x glasses are quenched to ambient temperature from Tcrl and reheated, they exhibit the phenomenon of double glass transition.
