Einstein in his paper introduced the term "energy
quanta" termed "photons" by chemist G. N. Lewis, in
1926. Later Compton, in his famous experiment proved
that light quanta have particle properties, or photons
elementary particles. At present time, the attention of
physicists is concentrated to the planar physics at zero
temperature and in the strong magnetic feld. Namely, in
the graphene physics which is probably new revolution in
this century physics with assumption that graphene is the
silicon of this century.
