Abstract
In this study, we investigate the thermoelectric transport properties of bilayer phosphorene under a composite magnetic and electric field (Ez and Bz). The complete Landau level spectrum and the real-space Landau wavefunctions are obtained using the generalized tight-binding model, which simultaneously considers the effects of geometrical structures, atomic interactions, and external fields. To our knowledge, this is the first study that uses spatially distributed subenvelope functions based on real sublattices to calculate the transition rate of Landau states in a truly two-dimensional system. The results show the nonmonotonic dependences of conductivity on the Fermi level, Ez strength, and direction, which enrich the thermopower and Nernst signal behaviors.
