"performance below those gallium arsenide-based, due to electronic disorder, being sensitive to stray electric fields from charged defects in surrounding materials... stacking 2 additional graphene layer ultra-thin electrostatic screens, with large relative twist angle ensuring layers electronically decoupled while separated <1 nm, 1 layer then doped to act as metallic screen suppressing charged impurities by order magnitude... other layer hexagonal boron nitride... sensing, quantum metrology, high-speed electronics/ computers"
