← TechnologyNear absolute zero, which outcome arises from resonant tunneling diodes biased closely?
A)Quantized conductance plateaus emerge✓
B)Thermal runaway rapidly escalates
C)Impurity scattering rate increases
D)Electron-phonon interactions strengthen
💡 Explanation
Quantized conductance results from quantum confinement within the quantum well and coherent transmission via resonant tunneling, because electrons can only pass if their energy aligns with the modes. Therefore, distinct conductance steps are observed, rather than a continuous range that scattering would induce.
