Note: Submicrometer-precision sample holder for accurate re-positioning of samples in scanning force microscopy

Area of Science:

• Materials Science
• Nanotechnology
• Microscopy

Background:

• Scanning Force Microscopy (SFM) requires precise sample positioning for accurate imaging.
• Current methods for sample manipulation and re-allocation in SFM can be complex and time-consuming.
• Integration of sample holders with piezoelectric scanners is crucial for enhanced control.

Purpose of the Study:

• To develop simple, compact, and high-precision sample holders for SFM systems.
• To enable automatic sample position recovery within submicrometer accuracy.
• To facilitate ex situ sample manipulation and subsequent SFM imaging of the same region without optical assistance.

Main Methods:

• Design and fabrication of two novel sample holder prototypes.
• Integration of kinematic mounting principles or self-adjusting mechanisms.
• Testing of sample position recovery accuracy and repeatability.

Main Results:

• Achieved automatic sample position recovery within approximately 100 nm.
• Demonstrated successful integration into a standard SFM system.
• Validated the ability to perform ex situ manipulation and re-image the same sample area without optical microscopes or positioning marks.

Conclusions:

• The developed sample holders provide a significant improvement in ease of use and precision for SFM.
• These holders streamline workflows by eliminating the need for tedious re-allocation and optical alignment.
• The designs offer a practical solution for researchers requiring accurate sample handling in SFM applications.
