← ScienceWhich outcome disables a scanning tunneling microscope when molecular vibrational energy changes a surface function?
A)Decreased tunneling current detected✓
B)Increased probe tip conductivity
C)Reduced thermal expansion artifacts
D)Enhanced plasmon resonance observed
💡 Explanation
The surface atoms' displacement alters the potential barrier width, changing the Transmission Probability and decreasing tunneling, because the vibrational changes affect the tunneling exponentially; therefore, a lower tunnel current is reported, rather than alternative effects at the sensor loop.
