Abstract
We report here measurements of electron tunneling through thin AlN films in which the imaginary component of the propagation vector in the forbidden band has been determined as a function of energy from the dependence of the tunneling current upon insulator thickness. The relationship so derived agrees well with Franz's empirical relationship for a material with the 4.2-eV forbidden-band energy of AlN. These results allow the prediction of voltage-current characteristics over the entire range of experimental variables with no arbitrary adjustable parameters, and also subject to several internal self-consistency checks. In each case complete consistency is observed, To the authors' knowledge, this represents the first unambiguous demonstration of such consistency in thin-film tunneling.
