During a Hall voltsge meaurement experiment, ifnthe meadure electric field is 5 V/m and the height of the semiconductor is 2 cm, then estimate the Hall voltage

Consider four of semiconductor samples: solid A is orange, solid B is black, solid C is white, and solid D is yellow. Given their colors, rank these semiconductors in order of increasing band gap. A. B < A < D < c B. B < D < A < C C. C < D < A < B D. C < A < D < B

Consider silicon at T =300 k is doped with donor impurities No = 2.8 × 101⁹ atoms / cm3 and Nc -2.8×101⁹ cm-³ 1. Draw the energy band diagram for this semiconductor and label all the energy levels? 2. What is the type of semiconductor?
