Introduction
Standard Overview and Technology Evolution
JY/T 0582-2020, as a general standard for scanning probe microscope (SPM) analysis methods, integrates the technical requirements of multiple national standards such as GB/T 27760-2011. This standard systematically regulates the standardized operating procedures of seven working modes, including contact mode and tapping mode, for the first time.
Classification and Principle of Core Instruments
| Instrument Type | Working Principle | Resolution Range | Typical Applications |
|---|---|---|---|
| Scanning Tunneling Microscope (STM) | Quantum Tunneling Effect | 0.1nm(lateral) | Atomic Structure of Conductor Surface |
| Atomic Force Microscope (AFM) | Probe-Sample Interaction Force | 1nm(lateral) | Surface Morphology of Insulator |
Detailed explanation of key operating specifications
Environmental control requirements
Chapter 5 of the standard clearly stipulates that the laboratory should maintain an ambient temperature of 20℃±5℃ and a relative humidity of ≤60%. Vibration interference must be controlled below 1μm amplitude.
Calibration process
Taking atomic force microscope as an example, Appendix B of the standard explains in detail:
- Use standard grid samples for XY direction calibration, the deviation should be <4μm
- Use step height standard samples in the Z direction, and the error must be controlled within ±2%
- Force constant calibration requires thermal tuning method, repeat the measurement 3 times and take the average
Implementation recommendations
Data quality control
Standard Article 9.2.1 recommends:
- Collect images of at least 3 different areas for each sample
- The scanning size should include the macroscopic morphology of 500μm×500μm and the microscopic structure of 1μm×1μm
- Force curve measurement requires baseline correction and thermal drift compensation
Troubleshooting
For the typical faults pointed out in Chapter 7:
| Fault phenomenon | Possible cause | Solution |
|---|---|---|
| Image stripe noise | Probe contamination/vibration interference | Replace probe/activate isolation table |
| Drift in Z direction | Unbalanced thermal expansion | Measurement after 30 minutes of warm-up |
