By layering different two-dimensional materials,
physicists at the University of Basel have created a novel
structure with the ability to absorb almost all light of a selected
wavelength. The achievement relies on a double layer of molybdenum
disulfide. The new structure’s particular properties make it a
candidate for applications in optical components or as a source of
individual photons, which play a key role in quantum research. The
results were published in the scientific journal Nature
Nanotechnology.
