Further modulations revealed that the junction formation probability and rupture distance of the molecular junction, which reflect the junction stability, will significantly influence the amplitude and position of the obtained conductance peak. We further extend our model to a diffusion and a chemical ...
The gap value determined from thepeak-to-peak of the conductance, $\\Delta_{p-p}$, exhibits a jump-like increaseas $T$ is raised across the critical temperature. The magnitude of the jump,the pseudogap opening temperature and superconducting gap decrease with raisingdoping. The $\\Delta_{...
When the junction is closed, conduction takes place over a few of the junction's atoms and exhibits a quantized conductance that is a multiple of conductance quanta G0= 2e2/h. When the junction breaks and a gap is formed between the electrodes, the conductance drops exponentially with the ju...
Chapter 4 shows a comparison of conductance of four conjugated oligomers at the single molecule level. In Chapter 5 we demonstrate the immobilization of a newly synthesized molecule with the potential of a molecular switch in the break junction....
Moreover, additional electrochemical gating provides a unique opportunity to manipulate the energy alignment and molecular redox processes for a single-molecule junction. In this review, we start from the technical aspects of the break junction technique, then discuss the molecular structure-conductance ...
junction. Under a fixed bias (100 mV), the current through the junction was recorded and is used for the further analysis.Figure 1bshows the typical conductance traces plotted on a logarithmic scale. The plateaus with a conductance value belowG0(conductance quantum) are assigned to molecular ...
A mechanical controllable break junction with an integrated liquid cell is used as the measurement tool. We first studied the influence of different solvents on the conductance of gold junctions in the regime of tunneling and true metallic contacts. These measurements served as control experiment for...
A slight increase in the tilting angle of the molecule was also observed by noting the increase in the energies of Raman modes and the decrease in conductance of the molecular junction. 展开 关键词: Pyridines Solutions Spectrum Analysis, Raman Temperature Molecular Dynamics Simulation ...
We present a theoretical study of the quasiparticle and subgap conductance of generic $X/I_{sf}/S_{M}$ junction with a spin-filter barrier $I_{sf}$, where ... FS Bergeret,A Verso,AF Volkov - 《Physics》 被引量: 15发表: 2012年 Writing spin in a quantum dot with ferromagnetic and...
Fullerenes are considered anchoring groups for molecular electronics due to a large contact area and their affinity for noble metals. The conductances of fullerene-terminated molecules, however, are found to be even lower than for thiol termination. The effects of weak molecule–metal coupling and ...
