Solid state physics

The Hall effect A magnetic field (in positive z-direction, magnetic flux density 0.1T) flows through an n-doped semiconductor with a length of 4cm, width of 2cm and a thickness of 0.1 mm. A voltage of 0.5V and a resistance of 1K0 are measured on the long side. The Hall voltage that is measured is 0.1 mV. a) In which direction does the opposing E-field point? What polarity does it have? b) Determine the charge carrier concentration. C) Determine the mobility. d) An intrinsic semiconductor is now used. How doesthe the direction of the electric field change? )d" YL
