The luminescence spectrum of excitons in ReS2 resembles the transitions in a free atom (Rydberg series), except that some transitions are missing, they are “dark”.

We explored magnetic and structural properties of multifunctional chiral nanocomposites based on magnetic nanoparticles and achiral liquid crystals. Our magnetoresponsive nanoparticles provided a stable nanocomposite when dispersed in achiral liquid crystals, giving rise to chiral supramolecular structures that can respond to UV-light illumination.

Through advanced experimental techniques, including cryomagnetic Raman spectroscopy, we derived a pressure-temperature phase diagram on CrI3.

The new concept of 2D laser based on superradiant emission opens up completely new possibilities for constructing ultra-thin radiation sources, the wavelength of which can be tuned by the number of layers of 2D semiconductor and boron nitride external electric and magnetic fields.
