Graphene-boron nitride heterostructures propagate light at the nanoscale

International research undertaken by scientists from ICFO and CIC nanoGUNE, amongst other centres, has enabled compressing light into small devices and controlling their flow of electricity, thanks to the union of graphene and boron nitride (a good bidimensional insulator). Such a promising heterostructure...

Stable long term operation of graphene devices achieved

Graphene based devices have shown outstanding electrical and optical performances. However, the properties of graphene devices are extremely sensitive to environmental factors, such as humidity or gas composition, making a reproducible operation in normal atmosphere impossible so far. Researchers from AMO GmbH and Graphenea SE have now demonstrated...
