← ScienceWhich outcome compromises silicon MOSFET performance at cryogenic temperatures?
A)Freeze-out of dopant atoms✓
B)Superconductivity onset in lattice
C)Increased electron-phonon scattering
D)Thermal runaway of junction voltage
💡 Explanation
Cryogenic temperatures cause freeze-out of dopant atoms because decreasing temperatures decrease the thermal energy available to ionize dopants, therefore reducing the number of charge carriers within depleted regions of the p-n junction, rather than causing superconductivity.
