A semiconducting crystal 12mm long, 5mm wide and 1mm thick has a magnetic flux density of 0.5Wb/m2 applied from front to back perpendicular to largest faces. When a current of 20mA flows length wise through the specimen, the voltage measured across its width is found to be 37μV. What is the Hall coefficient of this semiconductor?
Calculate the drift current in silicon at room temperature. If the intrinsic carrier concentration of (1x1016electron/m?) with the doping concentration of (2x1016atoms/m³) of the phosphorus and (1×1016atoms/m³) of Boron. Given the mobility for the electrons (0.15m2/V.s), the mobility for the holes (0.05m2/V.s), the electric field (100V/m), and the cross section area is 1mm?.
The intrinsic carrier concentration of silicon (Si) is expressed as - E n₁=5.2×10¹5T¹.5exp- i electrons at 30°C. n = cm -3 g 2kT cm -3 where Eg = 1.12 eV. Determine the density of Round your answer to 0 decimal places.
