Popis: Hall electrical conductivity is studied with relaxation time approximation based kinetic theory framework for metallic and graphene-like cases within a strong magnetic field-limit. A simple inversely proportional dependence on magnetic field in classical case is transformed to a complex field-dependent counterpart due to Landau quantization for quantum case. The order of magnitude of normalized conductivity is compared with the corresponding experimental values of graphene systems, which can be reduced to the order of \({e}^{2}/h\) due to quantum Hall effect.
