← ScienceWhich phenomenon in semiconductor devices is limited by the uncertainty in determining position and momentum functions of electrons?
A)Quantum tunneling through potential barriers✓
B)Electron-hole recombination rate at junctions
C)Ohmic contact resistance at metal interfaces
D)Dielectric breakdown strength of insulators
💡 Explanation
When uncertainty of location and momentum of an electron increases because of position and momentum limitations with semiconductors, quantum tunneling occurs because this directly modulates tunnelling behaviour. Increased uncertainty affects tunnelling amplitude functions. Therfore quantum tunneling is most related, rather than dielectric breakdown which stems from breakdown voltage.
