Editing Quantum tunnelling (section)

==== Electronics ====
Tunnelling is a source of current leakage in [[very-large-scale integration]] (VLSI) electronics and results in a substantial power drain and heating effects that plague such devices. It is considered the lower limit on how microelectronic device elements can be made.<ref>{{Cite web |title=Applications of ''tunneling'' |url=http://psi.phys.wits.ac.za/teaching/Connell/phys284/2005/lecture-02/lecture_02/node13.html |access-date=2023-04-30 |website=psi.phys.wits.ac.za}}</ref> Tunnelling is a fundamental technique used to program the floating gates of [[flash memory]].
