“…The results can be compared to those arising from a recent calculation 23 on Te 1−x I x based upon empirical potentials derived from the static structure factors. In the limit of low iodine concentration the value calculated as an extrapolation to x − → 0 yields 1700 m s −1 .…”

The spectra of collective excitations of liquid and glassy tellurium have been studied by means of inelastic neutron scattering. Here we report on the dynamics of liquid Te as measured at two different temperatures, just above melting ͑T m = 723 K͒ and at ϳ1000 K as well as the glass that is studied at room temperature. Estimates for the velocity of propagating excitations for both temperatures have been obtained from the experimental data, and a contrasting behavior is found with respect to anomalies shown by the adiabatic sound velocity measured by ultrasound methods. The origin of such differences is finally discussed.

“…The activation energies for double stage glass transition and crystallization are evaluated [6][7][8][9][10] using Kissinger equation and other approximations (equations 1-4 ). decrease of values in almost all cases [14][15][16], while the values obtained by other approaches seems to be consistent.…”

The crystallization kinetics of Se Sb Te chalcogenide glasses has been discussed under nonisothermal conditions using differential scanning calorimetry (DSC). DSC thermograms of these compositions exhibit double stage glass transition and crystallization .From the heating rate dependence of glass transition temperatures(Tg-1&Tg-2) and the crystallization temperatures (Tp-1&Tp-2), the values of the activation energies for glass transition(Eg-1&Eg-2)and that of crystallization (Ep-1&Ep-2) are evaluated using different theoretical models.

“…Depending on the composition, the chalcogenide glasses are [11][12] stable against crystallization and are chemically inert. They have excellent thermal stability, [13] and are relatively easy to fabricate.…”
