Tungsten probes come in many varieties, depending on their application and environment. Here are some possible tungsten probe types:
1. Tungsten probes used in electron microscopes: Tungsten probes used in electron microscopes are usually nanoscale tips used for high-resolution electron microscope imaging.
2. Scanning Tunneling Microscope (STM) Probes: STM probes are typically made of conductive materials, with tungsten being a common choice. This probe is used for surface imaging and study of electronic states at the atomic scale.
3. Tungsten probes in mass spectrometers: In analytical instruments such as mass spectrometers, tungsten probes may be used for sample ionization and analysis.
4. Tungsten probe in atomic force microscope (AFM): In atomic force microscope, the probe that probes the surface can be made of tungsten to achieve nanoscale surface topology imaging.
5. Tungsten probes in materials research: Tungsten probes used in materials research can have different shapes and sizes and are used to study the mechanical, thermal and other properties of materials.
