The extremely low coupling between chains, simple and explicit analytical expressions were derived. Results showed the field dependence of some physical properties in coupling chains. It was also shown that the Esaki-Tsu peaks were controlled by changing the magneic flux per cell. 关键词: Semiconductor superlattices;Electric currents;Quantum theory;Nanostructured materials;Electron scattering;Electrons;Fourier transforms;Eigenvalues and eigenfunctions;Hamiltonians;Magnetic flux;Magnetic field effects;Electric field effects;Coupled chains
