High-precision tungsten nano-needles usually refer to tungsten needle-shaped instruments that have undergone a special manufacturing process and whose tip processing accuracy reaches nano-level. This type of tungsten needle is used in applications where extreme tip precision is required and nanoscale manipulation or processing is required.
Here are some possible features and application scenarios:
1. Nanotechnology research: In research in the field of nanotechnology, high-precision tungsten nano-needle can be used to manipulate, measure or prepare nanoscale structures.
2. Scanning tunneling microscope (STM): In STM, a tungsten needle is often used to scan the surface, and high-resolution imaging of the sample surface is achieved by measuring current changes, which is very critical for nanometer-level surface structure research.
3. Nanobiological research: In nanoscale research in the field of biology, high-precision tungsten nano-needle can be used to perform fine operations on biological samples.
4. Semiconductor nanoprocessing: In the semiconductor industry, nanoscale processing is crucial for manufacturing nanodevices and chips, and high-precision tungsten nano-needle may be used in such processes.
