Amorphous sulfur (a-S) with excellent stability is obtained by rapid compression method. The prepared a-S has a single glassy phase and exhibits a wide supercooled liquid region of 112 K and much high thermal and kinetic stability at room temperature compared to that of conventional a-S fabricated by quenched method. The substantial improved thermal and kinetic stability is attributed to low energy state induced by rapid compressing process. The stable a-S is a model system for facilitating the studies of the nature of glasses and supercooled liquids.

    Supercooled liquids exhibit a pronounced slowdown of their dynamics on cooling without showing any obvious structural or thermodynamic changes. Several theories relate this slowdown to increasing spatial correlations. However, no sign of this is seen in standard static correlation functions,...
