Nanoscale Devices for Rectification of High Frequency Radiation from the Infrared through the Visible: A New Approach
Figure 16
Rectification ratio of a junction made of silver and subject to an external bias , with , 0.1 and 0.01 V (downwards, as indicated). The solid, dashed and dot-dashed lines indicate results indicate results achieved respectively with , , and as models for the dielectric function of the tip. Results obtained at the 3.1 eV resonance energy with as model for the dielectric function of the tip are not represented [19].
