DESCRIPTION:Speakers: Stefano Marchesin\n\n\nPhoto-induced fluidity is a p
 henomenon where a material's viscosity or structural rigidity decreases si
 gnificantly upon exposure to light. Chalcogenide glasses are known to exhi
 bit a variety of photoinduced phenomena included photofluidity. X-ray Ph
 oto Correlation Spectroscopy (XPCS) was used to probe X-ray induced fluidi
 ty for different Ge(x)-Se(1-x) glasses\, these results were then compared 
 with literature data obtained using sub-band-gap radiation. This compariso
 n shows that photo-induced fluidity is mainly determined by the dose-rate 
 deposited in the glass\, enlightening the common nature of the effect over
  a broad range of energies (eV for visible light and KeV for X-ray). Resid
 ual effects not accounted for by the dose-rate can be explained in terms o
 f a different efficiency of photo-induced effects across the energy gap of
  these glasses.\n\n \n\nhttps://indico.dfa.unipd.it/event/1852/
