Researchers have observed the fractional quantum Hall effect in a thin semiconductor material without the need for a magnetic field. This phenomenon, which involves the splitting of electrons into new particles called anyons, has potential applications in quantum computing. The findings were reported in three papers in Nature and one in press at Physical Review X.
Researchers at ETH Zurich have discovered a new mechanism for creating efficient nanoscale light sources by placing a semiconductor material outside the tunnel junction. By experimenting with the placement of tungsten disulfide, the researchers found that the semiconductor acted as an antenna, absorbing and re-emitting the energy created in the tunnel junction. This unexpected positioning resulted in improved light emission, although further improvements are needed. If successful, these nanoscale light sources could be a thousand times smaller than the wavelength of the light they produce, opening up new applications in data transfer and other technologies.
