Relationship between the stationary‐state and first‐order transfer‐Hamiltonian tunneling models

摘要

An equivalence of the expectation of the flux operator for the structure eigenstates of a tunneling junction to the square of the matrix elements of the flux operator evaluated between different structure eigenstates is discussed. The results are employed to elucidate the relationship between the stationary‐state model and the transfer‐Hamiltonian model of the junction current.
