Researchers create ‘extremely small’ sensor using ‘white graphene’

Researchers from TU Delft in the Netherlands, in collaboration with a team at the University of Cambridge, have found a way to create and clean tiny mechanical sensors in a scalable manner.

They created these sensors by suspending a two-dimensional sheet of hexagonal boron nitride (h-BN), or “white graphene” over small holes in a silicon substrate. This innovation could lead to extremely small gas and pressure sensors for future electronics.

Hexagonal boron nitride (h-BN) is an interesting material, since it has a honeycomb lattice structure similar to that of graphite. But while graphite conducts electricity, h-BN acts as an insulator.  Continue reading Researchers create ‘extremely small’ sensor using ‘white graphene’
