Introduction: A New Era in Nanoscale Analysis
In the fast-evolving world of material science, semiconductor development, and energy research, precision and correlation are everything. Traditional analytical techniques often require transferring samples between instruments, risking contamination, misalignment, or data inconsistency.
But what if you could analyze a sample in real-time, under the same conditions, and with multiple imaging modalities—all in one place?
This is where in-situ Atomic Force Microscopy (AFM) in Scanning Electron Microscopy (SEM) comes in.
By integrating AFM directly into an SEM chamber, this technology enables simultaneous, correlative imaging that unlocks unprecedented insights into nanoscale properties.
At EXPERTA | TESTING, we recognize the transformative potential of this approach for industries where accuracy, efficiency, and depth of analysis are non-negotiable.
What Is In-Situ AFM in SEM?
Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM) are both powerful tools, but they traditionally operate separately.
- AFM excels at measuring surface topography, mechanical, electrical, and chemical properties at the nanoscale
- SEM provides high-resolution imaging of surface morphology.
In-situ AFM in SEM combines these two techniques into a single, integrated system.
Using Correlative Probe and Electron Microscopy (CPEM), researchers can:
- Simultaneously acquire AFM and SEM data in the same environment.
- Correlate 3D topography with material properties (mechanical, electrical, chemical, magnetic).
- Analyze samples in real-time, without exposing them to ambient conditions, eliminating contamination risks.
This in-situ approach ensures that measurements are taken at the same time, in the same place, and under identical conditions—a game-changer for sensitive samples and dynamic processes.
What Makes This Technology Special?
1. Correlative Multimodal Analysis
With AFM-in-SEM, you’re not just seeing the surface—you’re understanding it.
The technology allows for:
- Seamless correlation of AFM (topography, mechanical, electrical) and SEM (morphology) data.
- 3D imaging that reveals hidden properties, such as conductivity, elasticity, or magnetic domains.
- Comprehensive sample characterization in a single workflow, reducing the need for multiple instruments and sample transfers.
2. In-Situ Sample Characterization
Sensitive samples - such as biological materials, batteries, or semiconductors - can degrade or change when exposed to air.
AFM-in-SEM eliminates this risk by:
- Keeping samples in a controlled environment (e.g., vacuum, specific gases).
- Enabling real-time observation of dynamic processes, like chemical reactions, mechanical stress, or thermal changes.
- Preventing contamination, ensuring data integrity.
3. Precise Localization of Regions of Interest
One of the biggest challenges in nanoscale analysis is finding the exact spot you want to study.
AFM-in-SEM solves this by:
- Using SEM’s high-resolution imaging to navigate the AFM tip directly to the target area.
- Saving time by avoiding the trial-and-error of traditional sample transfer methods.
- Enabling highly targeted measurements, even on nanostructures like quantum dots, thin films, or defect sites.
Who Can Benefit from AFM-in-SEM?
This technology is a game-changer for industries where nanoscale precision and multimodal analysis are critical.
1. Semiconductor Industry
“It accelerates defect analysis and material development for our engineers”
Why it matters: As semiconductor devices shrink to nanometer scales, defects, material properties, and interface quality become make-or-break factors.
Key Applications:
- Defect Analysis: Localizing and characterizing electrical defects in CMOS chips that are invisible to SEM alone.
- Failure Analysis: Investigating delayered integrated circuits or FIB/GIS-modified surfaces.
- Material Development: Studying conductivity in microcrystalline silicon or 2D materials (e.g., MoS₂, graphene).
Advantages Over Traditional Methods:
- No sample transfer means no risk of introducing artifacts.
- Simultaneous electrical and topological mapping accelerates root-cause analysis.
2. Battery & Energy Research
“This unlocks insights into electrochemical processes”
Why it matters: The performance of batteries, fuel cells, and photovoltaics hinges on nanoscale structure and chemistry.
Key Applications:
- Cathode/Anode Analysis: Studying Li-Ni-O₂ powders or solid-state electrolyte interfaces in-situ.
- Thin-Film Optimization: Analyzing magnetic nanopatterning for energy storage devices.
- Degradation Studies: Observing real-time changes in electrode materials under cycling.
Advantages Over Traditional Methods:
- In-situ analysis captures transient states (e.g., lithium plating, SEI layer formation).
- Correlative imaging links morphology to electrochemical performance.
3. Material & Life Sciences
“Gives a deeper understanding of nanoscale behavior”
Why it matters: From biomaterials to advanced composites, understanding structure-property relationships is key to innovation.
Key Applications:
- Biological Samples: Imaging cells conjugated with nanoparticles without dehydration artifacts.
- Nanomaterials: Characterizing WSe₂ flakes, nanopillars, or modified surfaces (e.g., FIB-polished CdTe).
- Polymers & Coatings: Studying surface morphology and mechanical properties of paints or hydrogels.
Advantages Over Traditional Methods:
- Non-destructive testing preserves sample integrity.
- Multimodal data provides a holistic view of material behavior.
AFM-in-SEM vs. Traditional Techniques: Why It Wins
Feature | AFM-in-SEM | Separate AFM + SEM |
Sample Transfer | None (in-situ) | Required (risk of contamination) |
Data Correlation | Seamless (3D, multimodal) | Manual (time-consuming, less precise) |
Dynamic Analysis | Real-time (e.g., reactions, stress) | Static (post-process only) |
Localization Precision | High (SEM-guided AFM) | Low (blind navigation) |
