Abstract: Feedback-controlled electromigration (FCE) is employed to control metal nanowires with quantized conductance and create nanogaps and atomic junctions. In the FCE method, the experimental parameters are commonly selected based on experience. However, optimization of the… read more here.

Abstract: By characterizing and manipulating the conductive properties of single Ag nano-grain boundaries with electromigration—originally considered only as a detrimental effect for metallic nanostructures—we show that atomic point contacts can be generated at well-defined locations with… read more here.

Abstract: Feedback-controlled electromigration (FCE) is employed to control metal nanowires with quantized conductance and create atomic junctions. The FCE scheme is commonly implemented using many experimental parameters, and determining the optimal FCE parameters can be regarded… read more here.
