Advanced Functional Materials, EarlyView.Single‐crystalline LaOCl and GdOCl form atomically abrupt, Cl‐terminated interfaces with MoS2, enabling near‐ideal switching and suppressed flicker noise. Carrier‐number‐fluctuation analysis yields effective noise‐derived interface trap densities of 1.15–1.94 × 1010 cm−2 eV−1, approaching hexagonal boron nitride levels with high‐κ coupling.
