The mechanically controlled break junction (MCBJ) technique is an approach to contact (electrically) individual molecules. The idea is to fabricate nanocontacts by pulling a ductile metal wire until it narrows down and eventually breaks.

2017年5月24日 · In this review, we mainly present the development of state-of the-art of mechanically controlled break junctions. Three-terminal gated MCBJ approaches are introduced to manipulate the electron transport of molecule, and combinations of …

2023年6月20日 · We used the MCBJ technique based on a microfabrication chip to demonstrate that the orientation of the single-molecule junction plays a critical role in the electrical control of the keto-enol ...

Using mechanically controllable break junctions (MCBJ), we study the ionic response in nanogaps with widths ranging from a few nanometers to millimeters. Moreover, we obtain an expression for the ionic current by solving time-dependent Nernst–Planck and Poisson equations.

2018年8月24日 · Optical and SEM images of fabricated crack-defined break junctions (CDBJ) depicted in a range from the nano-scale (sub-3 nm gaps) to the macro-scale (100 mm diameter wafer).

The threeterminal gated MCBJ approaches are introduced to manipulate the electron transport of molecules, and MCBJs are combined with characterization techniques.

Figure 2 a shows the scanning electron microscopy (SEM) image of a representative MCBJ sample whose size of the suspended constriction part is approximate 40 nm × 40 nm. This constriction will...

We have developed a combined Surface-enhanced raman spectroscopy (SERS) and mechanically controllable break junction (MCBJ) method to detect and characterize molecular junctions formed by two electrochemically nanofabricated electrodes on silicon chips.

I) A variant of MCBJ: single‐step bending‐deformation‐induced break junction, in which the nanogap electrodes are created and controlled by bending the electrode films with metal rods of ...

2013年3月17日 · We have investigated the influence of the metal electrodes on the energy levels in single-molecule junctions using two- and three-terminal mechanically controllable break junctions (MCBJs) in...
