Resumen:
We present ac conductivity spectra of telluritie glasses at several temperatures. For the first time, we report oscillatory modulations at frequencies around MHz. This effect is more pronounced the lower the temperature, and washes out when approaching the glass transition temperature Tg. We show, by using a minimal model, how this modulation may be attributed to the fractal structure of the glass at intermediate mesoscopic length scales. the fractal structure of the glass at intermediate mesoscopic length scales.
