Don't underestimate undulating graphene: Unique electronics made possible by wavy patterns that channel electrons

https://phys.org/news/2022-03-dont-underestimate-undulating-graphene-unique.html

"growing atom-thick graphene on a gently textured surface creates peaks and valleys in the sheets that turn them into "pseudo-electromagnetic" devices... promise a way to achieve a Hall effect — a voltage difference across the strongly conducting graphene —that could facilitate valleytronics applications that manipulate how electrons are trapped in "valleys"... in valleytronics, electrons have degrees of freedom in the multiple momentum states (or valleys) they occupy. These can also be read as bits"
