Abstract
In a recent report, Huang, Wu, and Gong [Phys. Rev. B 55, 11018 (1997) ] studied numerically the electronic properties of a random dimer mode l (RDM) and found extended periodic wave functions near the critical e nergies. We argue that there are no periodic wave functions in the RDM but close to the critical energies there exist periodic envelopes. Th ese envelopes are given by the nondisordered properties of the system.
