Stripe phases in WSe2/WS2 moir\'e superlattices

Understand

Stripe phases, in which the rotational symmetry of charge density is spontaneously broken, occur in many strongly correlated systems with competing interactions.

• One representative example is the copper-oxide superconductors, where stripe order is thought to be relevant to the mechanism of high-temperature superconductivity.
• Identifying and studying the stripe phases in conventional strongly correlated systems are, however, challenging due to the complexity and limited tunability of these materials.
• Here we uncover stripe phases in WSe2/WS2 moir\'e superlattices with continuously gate-tunable charge densities by combining optical anisotropy and electronic compressibility measurements.
