摘要: Scanning probe microscopy (SPM)-based approaches have been extensively studied as methods to control the structure and properties of materials on nanoscale. In many cases, SPM is physically utilized properties. addition physical modulation, it has reported that voltage can be effectively used modulate electrochemical phenomena sample surface. These studies suggest modulation possible by applying a voltage. Herein, in order demonstrate induced surface structure, we explored nanosculpting creating electrochemically pits TiO2 thin films through application using atomic force microscope tip. Using unipolar negative sweep, were successfully generated. Further, electric potential distribution was simulated unravel relationship between pit volume magnitude applied Finally, protrusion positive sweep also observed elucidate complete process modulation. results offer fundamental information for understanding how modulated phenomena.
