This property makes them valuable for applications such as non\u2010volatile random\u2010access memories, transducers, actuators and electro\u2010optic modulators. Recently, emergent unconventional ferroelectricity is demonstrated in moir\u00e9 superlattices of bilayer graphene and hexagonal boron nitride (hBN) hosting non\u2010centrosymmetric stacking order. Whether this phenomenon is also present in non\u2010centrosymmetric single layer graphene (SLG)\u2010hBN moir\u00e9 superlattices is still under debate. Here a ferroelectric response is demonstrated in an SLG\u2010hBN moir\u00e9 superlattice. Through Hall measurements, the origin of the hysteretic behavior is pinpointed to abnormal charge screening due to the moir\u00e9 superlattice band and the spontaneous polarization magnitude in the moir\u00e9 superlattice structure is estimated. Temperature dependent measurements confirm that the hysteretic behavior persists from 2K up to room temperature, opening opportunities for high\u2010mobility, ultrathin non\u2010volatile devices.<\/jats:p>","DOI":"10.1002\/smll.202508416","type":"journal-article","created":{"date-parts":[[2025,10,3]],"date-time":"2025-10-03T19:43:35Z","timestamp":1759520615000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Ferroelectric
