The fastest elements currently used to perform this function are silicon-based (the so-called RF silicon-on-insulator MOSFET ... called hBN (Hexagonal Boron Nitride), which allows its ON or ...

On the other hand, hexagonal boron nitride is a superb insulator with a largely flat surface, which is essential when combined with graphene or other 2D materials to form heterostructures.

A new technical paper titled “Resistive Switching and Current Conduction Mechanisms in Hexagonal Boron Nitride Threshold Memristors with Nickel Electrodes” was published by researchers at RWTH Aachen ...
