Abstract
3D graphene optical sensors, such as microstructure sensors and nanostructure sensors. The 3D optical sensors include one or more graphene panels shaped to surround an interior, open volume. Graphene plasmons couple across the interior, open volume. The 3D optical sensors can have a polygonal shape or a cylindrical shape.
Claims22
An optical sensor for detecting the presence of a foreign material, the sensor comprising:
- one or more panels shaped to surround an interior, open volume and including a graphene membrane;
- wherein graphene plasmons couple across the interior, open volume.
A method of fabricating an optical sensor, the method comprising:
- forming a 2D net including at least one panel having a frame supporting a graphene membrane;
- and
- subjecting the 2D net to thermal energy, causing the 2D net to self-transition into a 3D graphene sensor having an interior, open volume;
- wherein graphene plasmons couple across the interior, open volume.
