Area of expertise
The spheres of Yu.M. Chiang's scientific interests are transport phenomena in solid state, non–linear features in normal–metal conductivity, common and high–temperature superconductivity, quantum–interference phenomena in NS–systems, strongly electron correlations, spin-dependent electronic conductivity. In particular, he studied kinetic phenomena in normal metals (conduction–electron scattering under size effect conditions, at high magnetic fields, deformation, varying impurity concentration, etc.), investigated transmitted phonon–drag effect in metal sandwiches, experimentally revealed negative differential conductivity in a normal metal, observed the Bernoulli effect in superconducting Indium, discovered non–linear resistance of NS boundary, studied thermopower, conductivity and magnetic susceptibility of HTSC, proposed a way to study the spin-hall effect by electrical methods.
