FIG. 1.

Schematic diagram illustrating the mathematics of the intercept correction factor ρYX , as defined by Eq. (16) (but with the symbol CYX used instead of C). Curve L represents any nonelementary FN-type equation, plotted in FN coordinates of type [ln{Y/X 2} vs X −1)], and has the functional form L(X −1). The curvature of L is greatly exaggerated. Curve L cuts off at point "R," at which the field-reduced barrier height becomes zero. Line T is the tangent to curve L, taken at the "fitting value" X t. Line N shows how L(X t −1) is determined from curve L, when the pre-exponential of the FN-type equation has a value written in the form CYX (X t −1)X t 2. Line T intersects the vertical axis at value ln{I tan(X t −1)} and provides a second method of determining L(X t −1). The parameters CYX , I tan, σYX , and ρYX are all evaluated for X = X t.

TABLE I.

Values of the 2012 intercept correction function (r 2012) for the Schottky–Nordheim barrier, as a function of local work function ϕ and scaled barrier field f, for practical ranges of both parameters. Values of η as given by Eq. (7) are also shown.
