Single crystal Bi2Se3 was grown using the novel Bridgeman-Stockbarger method. Surface characteristics in terms of wear rate (W), wear coefficient (K), coefficient of friction (COF), and strain hardening exponent (n) were investigated using nanoindentation and nano scratch techniques. Our results revealed that the remarkable wear properties of single-crystal Bi2Se3 are promising for nanoscale design of topological insulators.
