An electron microscope (EM) is a type of microscope that uses an electron beam to illuminate a specimen and produce a magnified image.
Graphene is one of the most phenomenal materials discovered in science. It’s so thin, it can be molded into sheets just 1 atom thick, yet despite this, it’s so strong that you can actually pick it up. It has the highest current density (a million times that of copper) at room temperature, the highest intrinsic mobility [...]
Since they were first introduced more than 70 years ago, electron microscopes have aided researchers from a diverse array of fields of science reach some of the world’s greatest scientific breakthroughs – most often they’ve been considered indispensable. They’ve well reached their limits, however, and University of Sheffield researchers sought to find an alternate route for sub-atomic imaging. [...]
