# Experimental evidence on the Altshuler-Aronov-Spivak interference of the topological surface states in the exfoliated Bi2Te3 nanoflakes

@article{Qin2010ExperimentalEO, title={Experimental evidence on the Altshuler-Aronov-Spivak interference of the topological surface states in the exfoliated Bi2Te3 nanoflakes}, author={Yuyuan Qin and Zhaoguo Li and Fengqi Song and Qianghua Wang and Wangfeng Ding and Xuefeng Wang and Haifeng Ding and Baigeng Wang and Chris Van Haesondonck and Jian-guo Wan and Min Han and Yuheng Zhang and Guanghou Wang}, journal={arXiv: Mesoscale and Nanoscale Physics}, year={2010} }

Here we demonstrate the Altshuler-Aronov-Spivak (AAS) interference of the topological surface states on the exfoliated Bi2Te3 microflakes by a flux period of h/2e in their magnetoresistance oscillations and its weak field character. Both the osillations with the period of h/e and h/2e are observed. The h/2e-period AAS oscillation gradually dominates with increasing the sample widths and the temperatures. This reveals the transition of the Dirac Fermions' transport to the diffusive regime.
