Abstract
Refractive-index fluctuation in As2Se3 under excitation by an Ar+ lase
r was measured by an optical grating method. After 50 min exposition w
ith a power of 9.5 mW and diameter of the spot of similar to 0.25 mm,
the diffracted signal became considerably noisy. The Fourier transform
of the signal reveals a 1/omega spectrum, predicted for self-organize
d (ordered) electron-hole systems. (C) 1997 Elsevier Science B.V.
