Analysis of TCNQ-TTF molecular diodes
Description
Full text: The research discussed in this paper has focused on obtaining and testing the electronic properties of individual TCNQ (tetracyanoquinodimethane), TTF (tetrahiafulvalene), and TCNQ-TTF complex molecules, using scanning tunnelling microscopy techniques, namely scanning tunnelling spectroscopy (STS) and standard STM imaging. TCNQ and TTF are both known molecular organic semiconductors; TTF molecules are known to be electron donors, and TCNQ molecules are known to be electron acceptors. Some preliminary current-voltage (I-V) graphs of the mixed complex have been obtained showing that there is a clear asymmetry in the molecular I-V curves. This suggests these complexes act as molecular diodes
