Abstract
•Bi2Se3 single-crystal was grown by Bridgeman-Stockbarger method.•Single-crystal Bi2Se3 is capable of retaining most of its initial volume (≈94%) once subjected to wear.•COF value of the material is compatible to that of GaN, a common semiconductor.•Strain hardening properties measured using novel method based on pile-up height.
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.
