Dielectric Constants of Glasses in the System As-S-Se

Abstract

Dielectric const ants of glasses in the system As-S-Se have been measured in the fre q uency range 30 to 6Hz at room tem pera ture. It is sho wn that die•@lectric cons tants of the glas•@s samp•@ les are al most ind•@ep ende•@ nt of freq uency over the meas uring frequency range. Dielectric constants of the glass system As40S60-xSex with 0_??_x_??_60 at fixed frequency (300kHz) increase linearly with Se content, while those of the glass system Asx (S, Se) 100-x with 10_??_x_??_45 increase nonlinearly with As content and show a maximum peak at about 40 atomic % As and then decrease with As content.
