This breakthrough offers new possibilities for developing advanced quantum materials and devices.<\/p>\n<p>By precisely twisting two bilayers of WSe\u2082 near a 60-degree angle and applying a perpendicular electric field, the researchers have achieved control over the interaction between two distinct electronic bands, known as the K-valley and \u0393-valley bands. This tuning has led to the observation of a \u201cvalley charge-transfer insulator\u201d\u2014an exotic state where electron movement is highly correlated, and electrical conductivity is suppressed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A collaborative team of researchers from the Max Planck Institute for Structure and Dynamics of Matter (MPSD), Nanjing University, Songshan Lake Materials Laboratory (SLAB), and international partners has introduced a new method to regulate exotic electronic states in two-dimensional materials.
