Breakthrough in research on production of 2-D crystals with
excellent optical properties

For the first time, monolayers of transition metal
dichalcogenides with excellent optical properties were grown. A
team of physicists from the University of Warsaw managed to
overcome the technical difficulties faced by industry and
scientists from around the world—namely the very limited size,
heterogeneity, and broadening of the spectral lines of fabricated
materials. Monolayers without these defects were grown by molecular
beam epitaxy on atomically flat boron nitride
substrates.
