A theory from 2006 predicts that it should be possible to use graphene in a magnetic field not only to absorb terahertz and infrared light on demand but also to control the direction of the circular polarisation. Researchers now have succeeded in testing this theory and achieved the predicted results.
Researchers use a state-of-the-art electron microscope, the UltraSTEM, to manipulate strongly bound materials with atomic precision. Since the instruments used are fully computerized, it is possible to show in a simulation how researchers actually use them. This allows for compelling and largely realistic presentations of the most recent research in materials science.
Researchers have reported a truly single layer (i.e., adlayer-free) large area graphene film on large area copper foils. They refined the chemical vapor deposition (CVD) growth method by eliminating all carbon impurities inside the copper foils on which graphene is grown.
