Smit, G.D.J. (author), Rogge, S. (author), Klapwijk, T.M. (author)A generally applicable model is presented to describe the potential barrier shape in ultrasmall Schottky diodes. It is shown that for diodes smaller than a characteristic length lc (associated with the semiconductor doping level) the conventional description no longer holds. For such small diodes the Schottky barrier thickness decreases with...journal article 2002

Smit, G.D.J. (author), Rogge, S. (author), Klapwijk, T.M. (author)We have measured electrical transport across epitaxial, nanometer-sized metal–semiconductor interfaces by contacting CoSi2 islands grown on Si(111) with the tip of a scanning tunneling microscope. The conductance per unit area was found to increase with decreasing diode area. Indeed, the zero-bias conductance was found to be ? 104 times larger...journal article 2002
