Few-layer α-Sb₂O₃ molecular crystals as high-k van der Waals dielectrics: electronic decoupling and significant surface ionic behaviors

Abstract

Inorganic molecular crystal films, particularly α-Sb2O3, emerge as promising van der Waals (vdW) dielectrics for the large-scale integration of two-dimensional (2D) semiconductors in field-effect transistors (FETs) [Nat. Electron. 4, 906...
