Jiwoong Park, however, wondered what would happen if you made even thinner and flatter strands—in effect, so thin that they're actually 2D instead of 3D. What would happen to the light?
Lit up, the material 'sings.'" To arrive at their findings, the scientists sent pulses of light around the edges of these 2D materials using a ultrafast transmission electron microscope (UTEM ...
The team deciphered the mechanism responsible for the effect they found: Bound electron-hole pairs, so-called excitons, in 2D semiconductors rotate the polarisation of the light very strongly when ...
When laser pulses hit this flake, they generated excitons that moved into the nanotube and along its length, before releasing light of a longer wavelength than the laser. It took just one trillionth ...
