Why 2D? What is it about two-dimensional materials that makes them so interesting for future, low-energy electronics?
Constraining the movement of charge carriers (electrons or holes) to two dimensions unlocks unusual quantum properties, resulting in useful electronic properties. Much can be learned by observing precisely at what thickness such effects emerge, transitioning from a 3D system to a 2D system.
A study published last week quantifies the precise transition point in the promising material tungsten ditelluride (WTe2).
