| Outline of Final Research Achievements |
Here, we study the intelligent control approach for the tuning of feedback parameters of feedback-controlled electromigration (FCE) method using real-time operating system (RTOS), with cost functions to evaluate control quality of Au atomic junctions. We investigated the FCE evaluation system to tune the quantized conductance behavior of Au atomic junctions. First, the feature values of the conductance quantization were extracted from the conductance traces during the FCE procedure, and were stored in a database. Then, we evaluated the FCE parameters using cost functions. As a result, the conductances of Au atomic junctions formed with the highest score in the database were successfully quantized and discretely decreased with process time without catastrophic breaks. Therefore, the results imply that FCE evaluation system using intelligent control approach improves the controllability of quantized conductance of Au atomic junctions with appropriate feedback parameters.
