Microfabrication of a mechanically controllable break junction in silicon
We present a detailed description of the fabrication and operation at room temperature of a novel type of tunnel displacement transducer. Instead of a feedback system it relies on a large reduction factor assuring an inherently stable device. Stability measurements in the tunnel regime infer an electrode stability within 3 pm in a 1 kHz bandwidth. In the contact regime the conductance takes on ...
متن کاملContacting individual molecules using mechanically controllable break junctions
Among the experimental techniques employed in contacting individual molecules Mechanically Controllable Break Junctions are being frequently used. Some of the advantages are (1) straight-forward preparation of clean surfaces for anchoring the molecule; (2) the possibility to produce many different single-molecule junctions in one experiment, allowing obtaining statistical averages; (3) adapting...
متن کاملMechanically Steerable Array Antennas Using Controllable Microwave Phase Shifters
Low-cost antenna systems are important issues of the recent and the future flexible wireless communication systems. The most flexible satellite to ground/airplane communication systems are based on the phased-array antenna technology. However, the cost of phased array antenna is related to the number of active elements, and the present systems are too expensive for many commercial/military appl...
متن کاملTuning the Kondo effect with a mechanically controllable break junction.
We study electron transport through C(60) molecules in the Kondo regime using a mechanically controllable break junction. By varying the electrode spacing, we are able to change both the width and the height of the Kondo resonance, indicating modification of the Kondo temperature and the relative strength of coupling to the two electrodes. The linear conductance as a function of T/T(K) agrees w...
متن کاملA nonlinear field theory of deformable dielectrics
Two difficulties have long troubled the field theory of dielectric solids. First, when two electric charges are placed inside a dielectric solid, the force between them is not a measurable quantity. Second, when a dielectric solid deforms, the true electric field and true electric displacement are not work conjugates. These difficulties are circumvented in a new formulation of the theory in thi...
