Weak localization in 1 T − TiS e 2 microflakes

We have studied the electrical transport in the charge-density wave material $1T\\ensuremath{-}\\mathrm{TiS}{\\mathrm{e}}_{2}$ microflakes. In the low temperatures, the logarithmic temperature-dependent resistivity corrections were observed. In particular, the negative magnetoresistances in low magnetic fields were further measured and well described by the Hikami-Larkin-Nagaoka theory. All the experimental results demonstrate the weak localization effect in the $1T\\ensuremath{-}\\mathrm{TiS}{\\mathrm{e}}_{2}$ microflakes. Furthermore, the power-law dependence of the extracted phase coherence length on temperature is $\\ensuremath{\\sim}{T}^{\\ensuremath{-}0.6}$, indicating the presence of the two-dimensional electron-electron interaction in the $1T\\ensuremath{-}\\mathrm{TiS}{\\mathrm{e}}_{2}$ microflakes.
