A strip of silicon 1.6 cm wide and 1.0 mm thick is immersed in a magnetic field
Question:
A strip of silicon 1.6 cm wide and 1.0 mm thick is immersed in a magnetic field of strength 1.5 T perpendicular to the strip (Fig. 29-45). When a current of 0.28 mA is run through the strip, there is a resulting Hall effect voltage of 18 mV across the strip (Section 20-4). How many electrons per silicon atom are in the conduction band?
The density of silicon is 2330 kg/m3.
