Observation of $h/e$ conductance oscillations in disordered metallic   $T_3$ network
  We report on magnetotransport measurements performed on a large metallic two-dimensional $\mathcal{T}_{3}$ network. Superimposed on the conventional Altshuler-Aronov-Spivak (AAS) oscillations of period $h/2e$, we observe clear $h/e$ oscillations in magnetic fields up to $8 T$. Different interpretations of this phenomenon are proposed.
