Which effect results when electrons encounter nanoscale gaps?

💡 Explanation

Electron tunneling drives current across the gap because electrons exhibit wave-like properties, allowing them to pass through even when classically forbidden; therefore, considerable tunneling current arises, rather than backscattering in proportion to the gap size.
