Twisted bilayer graphene dances with light
When two layers of graphene are placed one on top of the other, and twisted among them by a very small angle, a “moiré pattern” is formed and the physical properties of the system have proven to change dramatically. In particular, near the ‘magic’ angle of 1 degree, the electrons slow down ... more
Determining the structure of a molecule with laser-induced electron diffraction
Light microscopes have revolutionized our understanding of the microcosmos, but their resolution is limited to about 100 nanometers. To see how molecules bond, break, or change their structure, we need at least 1000 times better resolution.
Laser induced electron diffraction (LIED) is a tec ... more
Graphene gives a tremendous boost to future terahertz cameras
Detecting terahertz (THz) light is extremely useful for two main reasons:
Firstly, THz technology is becoming a key element in applications regarding security (such as airport scanners), wireless data communication, and quality control, to mention just a few. However, current THz detectors ... more
