What is Extreme Precision in Nanotechnology?
Extreme precision in nanotechnology refers to the ability to manipulate and control materials at the atomic and molecular scale. This level of accuracy is essential for creating nanoscale devices and structures with desired properties and functionalities. Achieving such precision involves various techniques and tools designed to operate at scales of less than 100 nanometers.
Why is Extreme Precision Important?
Precision is critical in nanotechnology because even minor deviations at the nanoscale can lead to significant differences in the properties and behaviors of nanomaterials. For instance, the electrical, optical, and mechanical properties of nanomaterials can be highly sensitive to their size, shape, and composition. Therefore, achieving extreme precision ensures the reliability and performance of nanoscale devices and applications.
