Summary
We developed a new method to apply large strains to delicate electronic materials using piezoelectric actuators. This technique allows for precise uniaxial stress application, advancing materials science research.
Area of Science:
- Materials Science
- Condensed Matter Physics
- Solid State Physics
Background:
- Uniaxial stress is a key method for probing electronic materials.
- Current methods for applying stress have limitations, either allowing large strains on robust samples or delicate strains on fragile ones.
Purpose of the Study:
- To develop a novel method for applying large elastic strains to mechanically delicate samples.
- To merge the advantages of existing uniaxial stress application techniques.
Main Methods:
- Thin samples were affixed to a substrate.
- The substrate-mounted samples were subjected to uniaxial stress using piezoelectric actuators.
- This approach allowed for the application of tunable uniaxial stress.
Main Results:
- Demonstrated the successful application of large elastic strains to mechanically delicate samples.
- Successfully applied the method to van der Waals-bonded iron selenide (FeSe).
- Successfully applied the method to a focused ion beam-shaped cerium-gold-antimony (CeAuSb2) sample.
Conclusions:
- The described approach effectively combines the benefits of previous methods.
- This technique enables the study of mechanically delicate materials under significant uniaxial stress.
- The method is suitable for investigating materials like FeSe and CeAuSb2.
