Negative refraction of electrons spotted in graphene

The negative refraction of electrons in graphene has been seen for the first time in experiments done by physicists in the US. The work represents an important advance in the fabrication of graphene electronic devices, and could lead to new applications of graphene such as low-power transistors……… http://nanotechweb.org/cws/article/tech/66506 Wrong way: electrons undergoing negative refraction at […]

Graphene coating improves electron microscopy images

Researchers in Korea and the UK have discovered that a graphene coating on biological samples helps dissipate the charge build-up that normally occurs on the surface of these samples during non-destructive electron microscopy imaging. Such a charge build-up is usually a big problem in this context and prevents high-resolution images from being obtained…….. http://nanotechweb.org/cws/article/tech/66514 Graphene […]
