Many of the remarkable electrical and optical properties of organic semiconductors are governed by the interaction of electronic excitations with intra- and intermolecular vibrational modes. However, ...

Scientists have discovered an indicator that reliably demonstrates a sample's high quality, and it was one that was hiding in plain sight for decades. Producing structurally perfect graphene and other ...

Sir Robert Robertson, Dr. J. J. Fox and Dr. A. E. Martin showed in 1934 1 that in addition to the normal type of diamond, which is always optically anisotropic, there is a rarer type which is much ...
