摘要：
We consider the problem of finding the energy spectra, transmission and charge distribution on nanowires with scanning tunneling spectroscopy. Within this context, we first test the applicability of the method by comparing the output of our theory with available experimental results on In-based quantum Wells patterned oil nanowires. Then we study the correlation between density of states and electron transmission Curves. Third, we investigate the induction Of ultrafast electronic transitions due to the presence of a molecular switch or a scanning probe microscope tip. (C) 2008 Elsevier B.V. All rights reserved.
