Tīmeklis11.2 Hall Effect. The Hall effect is the deflection of electrons (holes) in an n-type (p-type) semiconductor with current flowing perpendicular to a magnetic field. The deflection of these charged carriers sets up a voltage, called the Hall voltage, whose polarity depends on the effective charge of the carrier. Tīmeklis2024. gada 12. apr. · The quantum efficiency starts to saturate when the applied voltage reaches ~−0.18 to ~−0.2 V. The peak quantum efficiency exceeds 100% as the applied voltage increases up to ~−0.5 V, corresponding to an IQE above unity over a broadband of the spectrum, as shown in Fig. 4D. This is due to the photoconductive gain effect, …
