Insulators for Transistors

Caption

Currently, only a small selection of insulators for extremely small transistors exists: SiO2 (right) is amorphous and has an undefined surface, hBN (middle) is crystalline but it is not a good insulator, CaF2 (left) is crystalline, has a clean surface, and is a very good insulator.
