Scientific paper

It is argued that self-duality of one system leads to the zero finite-size scaling amplitude of the critical internal energy for all system belonging to the same universality class. For such models, we may expect that condition of equality (up to correction-to-scaling terms) of the internal energies for systems with different sizes will yield more accurate estimates for the critical temperature than the scaling equation for the inverse correlation lengths which is used in the standard phenomenological renormalization-group approach. Analytical and numerical evidences confirming the above conjecture are given for examples of two-dimensional next-nearest-neighbour and spin-1 Ising lattices.
