B2O3 glass former as a molecular matter revealed by heat capacity
Heat capacity of B2O3 glass former in a wide temperature region is described well with the intrinsic motions for non-spherical B2O3 molecules, revealing that rather than a conventional network glass former, B2O3 is a typical molecular matter in which the transition from liquid to glass in the system corresponds to the frozen of translational motions for molecules. The finding might provide an opportunity to understand the mysterious glass transition, as well as the intrinsic difference between solids and liquids.
