What are the Challenges in Electron Optics for Nanotechnology?
One of the primary challenges is the control and manipulation of electron beams at such small scales. Factors like beam aberrations, electron scattering, and sample damage due to high-energy electrons can limit the effectiveness of electron optics techniques. Additionally, the need for vacuum environments and the potential for charging effects in non-conductive samples are significant hurdles. Advances in electron optics technology and techniques are continuously being made to overcome these challenges.
