TEMPERATURE-DEPENDENCE OF CONDUCTANCE OF FIBONACCI SUPERLATTICES

Studies of the dc conductance of Fibonacci superlattices at finite tem perature are carried out. Exact solutions of the Schrodinger equation are used for our treatment of the problem. The results show a strong d ependence of electrical conduction on the chemical potential, which ac ts as a probe of the underlying electronic structure. In particular, i t is found that the Fibonacci superlattice shows metallic behaviour wh en the chemical potential lies within allowed bands and it behaves as a semiconductor when the chemical potential lies within gaps.
