Mikhail (Michel) Dyakonov (born 1940 in Leningrad) is a Russian professor of physics at Laboratoire Charles Coulomb (L2C), Université Montpellier - CNRS in France.
His name is connected with several physical phenomena: Dyakonov–Perel spin relaxation mechanism, Dyakonov–Shur plasma wave instability.
Perel he predicted the Spin Hall Effect, which has become a field of intense studies.
[1][2] Unlike other types of acoustic and electromagnetic surface waves, the DSW's existence is due to the difference in symmetry of materials forming the interface.
These waves are important at the interface of a biaxial anisotropic dielectric with an isotropic medium,[3] metamaterials[4] and they have also found use in terahertz applications.
