“…Besides the prospect of forming topological insulators, incorporation of Bi or Sb into the structure of chalcogenides has a profound impact on their electrical properties [13,14]. These dopants are able to unpin the Fermi level and change the conduction from p to n type in chalcogenide glasses (which are known to be highly insensitive to metal doping [13,14]), and even cause a strong thermoelectric power effect [15,16]. The combination of these properties with high optical transparency (extending up to ~18 µm) and non-linearity [17,18], makes Bi/Sb-containing chalcogenide alloys a very appealing multifunctional medium for numerous applications in (nano)optics and (nano)electronics [19][20][21][22].…”

The non-isothermal crystallization kinetics of novel 3,5,10) glasses are studied with differential scanning calorimetry method, and analysed using Frazer-Suzuki fitting function. The applicability of Johnson-Mehl-Avrami (JMA) model to describe the crystallization kinetics in these materials is verified, and JMA exponent is determined for the relevant crystallization processes. It is found, that substitution of Sb with Bi in glass composition leads to a decrease in optical gap and thermal stability of the glass, and increase in the density and crystallization activation energy for glass-ceramics formation.
