Which consequence results when a scanning tunneling microscope tip contaminates an electron orbital?

A)Reduced tunneling current amplitude occurs
B)Increased resonant frequency is measured
C)Spin decoherence effects will increase
D)Auger electron emission efficiency decreases

💡 Explanation

Reduced tunnelling current amplitude occurs because orbital contamination introduces scattering, decreasing the electron's mean free path, therefore causing the reduction, rather than increased frequency shifts or Auger emission changes, which are effects happening with other distinct mechanisms.
