VALIDITY OF THE "GOLDEN RULE" FOR N-I-S TUNNELING

 

RASSMIDARA NAVANI AND I-MING TANG

Summary: The transmission coefficients for forward and backward tunneling in a normal metal-insulator-superconductor (NIS) junction are obtained via the Bogoliubov-de Gennes equations. The fact that the two transmission coefficients are different casts doubt on the validity of the "golden rule" used in the transfer hamiltonian approach to tunneling in NIS junctions.
