WebApr 10, 2024 · A band gap is a distance that is present between the valence band and the conduction band of electrons. Essentially, the band gap represents the minimum energy that is required to excite an electron up to a state in the conduction band where it can participate in conduction. The lower energy level is found in the valence band, and thus … WebDec 22, 2024 · At zero magnetic field, the Hall resistance ( Rxy ≈ 26 kΩ) is nearly quantized at h / e2 and the longitudinal resistance ( Rxx ≈ 1.3 kΩ) is substantially smaller ( h / e2 ≈ 25.8 kΩ is the ...
