melts and glasses across the Intermediate Phase.

We have examined the specific Heat C_p in the glassy state and the metastable liquid state across T_g in binary GexSe100-x system in the 19% < x < 26% range of compositions focusing on the Intermediate Phase. The bulk glasses used in the present Modulated DSC study were the ones synthesized by Bhosle et al.¹. Our results show C_p(glass) and C_p(liquid), each term to display a broad Gaussian-like maximum centered about the mid -point composition, x = 23%, of the Intermediate Phase. We are also investigating the variation of C_p(liquid) at higher temperature in the T_g < T < 550°C range to look at any anomalies that could be related to the liquid-liquid transition recently suggested².
