Abstract

To study the emergence of superconductivity in \(\mathrm{Na}_{2-\delta }\mathrm{Mo}_{6}\mathrm{Se}_6\), it is first important to understand the nature of its normal state. The presence of e–e interactions will influence the emergence and stability of the superconducting state. In \(\mathrm{Na}_{2-\delta }\mathrm{Mo}_{6}\mathrm{Se}_6\), the electronic structure calculations (Chap. 3) predict the electronic state to be 1D at \(T>120\) K and anisotropic 3D at \(T<120\) K. However, any e–e interaction renormalizes the hopping energies. The temperature range accessible in our different measurement systems allows us to study the dimensional crossover in the transport data.
