Which consequence results when a scanning tunneling microscope tip exceeds electron tunneling distance limits?

💡 Explanation

Increased proximity triggers **electron orbital overlap**; because more electron density is shared, this significantly increases the attractive van der Waals force. Therefore, the tip risks snapping to the surface rather than accurate imaging because stable tunneling is impeded by interatomic potentials.
