Reverse Monte Carlo simulations using neutron data show that the structure
of CuxAs0.45-xTe0.55 chalcogenide glasses (0.10 less than or equal to x les
s than or equal to 0.20) is well described by the continuous network model.
Cu substitutes randomly for As and the rigidity of the network increases w
ith increasing Cu concentration. (C) 2000 Elsevier Science B.V. All rights
