Abstract

The exotic correlated phases that emerge in the low-dispersing moir\'e bands of twisted van der Waals structures have opened new exciting opportunities in condensed-matter physics. These systems exhibit a rich phase diagram of novel physical phenomena and exotic correlated phases that emerge in the low-dispersing bands. Despite its popularity, the resulting mini-bands in the conduction band of ${\mathrm{MoS}}_{2}$ moir\'e superlattices remained elusive so far. In this work, we resolve these spin-valley mini-bands via transport spectroscopy in micron-scale devices. The theoretical energy scales exhibit an astounding agreement with our experimental observations, which together with the behavior under thermal activation, suggest an electronic phase transition. These intriguing observations highlight the potential of twisted ${\mathrm{MoS}}_{2}$ structures as a playground to explore correlated electron states and associated phenomena.
