Journal ArticleDOI
Mechanisms of current rectification in an STM tunnel junction and the measurement of an operational tunneling time
H.Q. Nguyen,Paul H. Cutler,T.E. Feuchtwang,Z.-H. Huang,Y. Kuk,P. J. Silverman,A.A. Lucas,T.E. Sullivan +7 more
TL;DR: In this paper, the effects of material, thermal, and geometrical asymmetries on the nonlinearity of the I-V characteristics of a scanning tunneling microscope (STM) tunneling junction are investigated theoretically and experimentally.
Journal ArticleDOI
Derivation of the image interaction for non-planar pointed emitter geometries: application to field emission I–V characteristics
TL;DR: In this paper, the authors derived closed form analytical solutions for the image interaction for tips modeled as a cone, paraboloid, hyperboloid, and sphere on cone have been derived.
Journal ArticleDOI
Wentzel-Kramers-Brillouin method in multidimensional tunneling
TL;DR: It is shown that for normal incidence the path equations are decoupled and are equivalent to Newton's equations of motion for the inverted potential and energy.
Journal ArticleDOI
Scattering-theoretic approach to elastic one-electron tunneling through localized barriers: Application to scanning tunneling microscopy.
A. A. Lucas,H. Morawitz,G. R. Henry,Jean-Pol Vigneron,Ph. Lambin,Paul H. Cutler,T.E. Feuchtwang +6 more
Journal ArticleDOI
A theory of vacuum tunneling microscopy
TL;DR: In this article, a general expression for the tunneling current for any two electrodes of arbitrary shape is derived and discussed, and a discussion of the resolution predicted by the theory is presented.
