Calculate the hall voltage when the magnetic field is 8 A/m, current is 4 A, width is 5 m and the concentration of carrier is 1020.
For an n-type Ge specimen, width = 4 mm, length = 1 mm, current (along the length of specimen) = 1 mA, magnetic field (perpendicular to the current flow direction) = 0.1 Wb/m2 and Hall voltage magnitude = 0.005 V. Calculate the majority carriers density.
For a particular material, the Hall coefficient is found to be zero. The material is
