Abstract

Bulk $Ge_xSe_{80-x}Pb_{20}$ glasses, which show a change from p- to n-type conduction around x = 21 at %, have been prepared by quenching the melt. The specific heat at constant pressure $(C_p)$ has been measured for these glasses using a DSC. These glasses exhibit minima in a jump in specific heat $(\Delta C_p)$ and the area under the peak at $T_g$ at x = 19 at %, where they show a minimum fragility. These results are discussed in the light of a chemical threshold in these glasses.
