New material helps record data with light

(ITMO University) Russian physicists with their colleagues from Europe through changing the light parameters, learned to generate quasiparticles -- excitons, which were fully controllable and also helped to record information at room temperature. These particles act as a transitional form between photons and electrons so the researchers believe that with excitons, they will be able to create compact optoelectronic devices for rapid recording and processing an optical signal.
