Disorder inevitably exists in realistic samples,manifesting itself in various exotic properties for the topological *** this paper,we summarize and briefly review the work completed over the last few years,including our own,regarding recent developments in several topics about disorder effects in topological *** weak disorder,the robustness of topological states is demonstrated,especially for both quantum spin Hall states with Z2 = 1 and size induced nontrivial topological insulators with Z2 = *** moderate disorder,by increasing the randomness of both the impurity distribution and the impurity induced potential,the topological insulator states can be created from normal metallic or insulating *** phenomena and their mechanisms are *** strong disorder,the disorder causes a metal-insulator *** to their topological nature,the phase diagrams are much richer in topological state ***,the trends in these areas of disorder research are discussed.
