Which consequence results when an electron encounters a sharply narrowing constriction within a semiconductor channel?

A)Quantized conductance staircase is observed
B)Ohmic behavior becomes strictly linear
C)Scattering probability exponentially decreases
D)Capacitance becomes frequency independent

💡 Explanation

A reduction in the channel width forces electron confinement which causes quantum effects; quantum confinement forms discrete energy levels; hence, steps in conductance are observed, because Conductance Quantization occurs rather than linear resistance, capacitance changes, or exponentially decreasing scattering.
