Nanopatterning electronic properties of twisted 2D semiconductors

Researchers have demonstrated that atomic lattices of slightly twisted 2D transition metal dichalcogenides undergo extensive lattice reconstruction, which can pattern their optoelectronic properties on nanometre length scale.

Photonic crystals: 'even thin is functional'

It was always thought that photonic crystals should be thick and bulky to be functional. Scientists now discovered that even very thin 3D photonic band gap crystals are powerful devices to strongly control the flow of light.
