Which risk increases when scanning tunneling microscope tip retracts?

💡 Explanation

Increased contamination results when an STM tip retracts because Van der Waals force allows the adhesion of stray atoms. This causes surface contamination, rather than quantization, reduced scattering, or ionization due to the absence of robust electric field interaction.
