Question

Transistors switched using this phenomenon, as opposed to thermal injection, are predicted to break the 60 millivolt-per-decade subthreshold swing limit currently impairing power scaling. A magnetoresistive effect named for this phenomenon is the operating principle of MTJs. A form of this phenomenon used to erase NOR flash memory chips is the mechanism for field emission. (10[1])This phenomenon causes the negative differential resistance of an Esaki diode. The current (10[1])due to this (10[1])phenomenon varies with the height of a metal tip above a sample in a form of microscopy. Alpha particles escape from the nucleus’s attractive potential via this process in Gamow’s model of alpha decay. For 10 points, name this quantum phenomenon in which a particle passes (10[1])through (10[2])a classically (10[2])forbidden barrier. (-5[1])■END■ (10[1])

ANSWER: quantum tunneling [accept tunnel FETs; accept tunnel magnetoresistance; accept Fowler–Nordheim tunneling; accept tunnel diodes; accept scanning tunneling microscopy]
