In this connection, it is possible that in the near future the next stage in the evolution of the world electronics will be <<optoelectronics>> in which a quantum quasiparticle without a rest mass appears as a photon, a much more mobile and less inertial in its physical nature, a representative of the microworld than a free electron (<<a hole>>) in a semiconductor crystal of solid-state electronics.
