SUBHARMONIC GENERATION IN GESBSE CHALCOGENIDE CANTOR-LIKE GLASSES
The purpose of this paper is to study the subharmonic wave propagation in GexSb40-xSe60 with composition 12, 25 and 30 at.%, synthesized from elements with 5N purity (Ge, Sb, Se) by the conventional melt-quenching method. The plate has a Cantor-like structure. The subharmonic generation of waves is due to the fractal features of chalcogenides with spectral scalability that lead to a nonlinear superposition of waves in both phonon and fracton vibration regimes.
