Transcribed Image Text:In a Hall experiment, a doped semiconductor sample is placed on the x-z plane, as shown
in Figure 1. The sample has a thickness t, a height ab = h and a width ad = w. The
magnetic field B is along the positive y axis and the current of I is injected along the
negative z axis. The voltage on the ab side is found to be AV higher than that on the cd
side. It is given that the equation dedicated to a n-type semiconductor is as follows:
