Figure C1.5.12.(A) Fluorescence decay of a single molecule of cresyl violet on an indium tin oxide (ITO) surface measured by time-correlated single photon counting. The solid line is tire fitted decay, a single exponential of 480 5 ps convolved witli tire instmment response function of 160 ps fwiim. The decay, which is considerably faster tlian tire natural fluorescence lifetime of cresyl violet, is due to electron transfer from tire excited cresyl violet (D ) to tire conduction band or energetically accessible surface electronic states of ITO. (B) Distribution of lifetimes for 40 different single molecules showing a broad distribution of electron transfer rates. Reprinted witli pennission from Lu andXie [1381.

An SWCNT a few microns long with electrical contacts deposited via nanolithography techniques is an ideal system to study single-molecule transistor effects, in which an electrode (Vga/e) close to the conducting CNT is used to modulate the conductance [33]. [Pg.120]

Due to the fact that K2TaF7 - KF is considered to be part of the TaF5 - KF binary system, while the K2TaF7 - KCI system is a component of the interconnected ternary system K+, Ta5+//F", Cl", the single-molecule conductivity and activation energy of the systems was calculated based on density and specific conductivity data [322, 324]. Molar conductivity (p) depends on the absolute temperature (T), according to the following exponential equation ... [Pg.153]

Chen et al. [201] investigated the single-molecule conductance of alkanes terminated with either dicarboxylic-acid, diamine, or dithiol anchoring groups. The contact resistance was again found to be dependent on the anchoring group, which varies in the order Au—S>Au—NH2>Au—COOH. [Pg.341]
