Glass forming ability of Te-Bi-Se based alloys

Abstract

In the present work, the relationships for the glass transition temperature <i>T_g, </i>the peak temperature <i>T_p, </i>and the difference of crystallization temperature and glass transition temperature, (<i>T_c</i> -<i> T_g</i>), for different heating rates have been studied with the increase in Bi content. With the increase in heating rates <i>T_g, T_c </i>and <i>T_p </i>are found to increase. The glass transition temperature represents the strength or rigidity of the glass structure. This analysis helps in finding the suitability of an alloy to be used in phase transition optical memories/ switches.
