Which outcome occurs when an STM tip approaches a non-conductive surface?

💡 Explanation

Electrons crossing a non-conductive gap use quantum tunnelling because an energy barrier exists. Therefore current flows even with a classically forbidden gap, rather than triboelectric charging dominating or thermal expansion being significant effects at that scale under normal conditions.
