Which outcome occurs when electrons in a Scanning Tunneling Microscope experience a small air gap?

💡 Explanation

Lower image contrast results because quantum tunneling allows electrons to pass through the air gap, rather than being reflected; therefore, contrast decreases because reflected current is less sensitive to surface height rather than chromatic aberration artifacts.
