Chapter 9, Problem 73P
The Hall effect is demonstrated in the laboratory. A thin rectangular strip of semiconductor with width 5 cm and cross-sectional area 2 mm" is attached to a battery and immersed in a field perpendicular to its surface. The Hall voltage reads 12.5 V and the measured drift velocity is 50 m. s. What is the magnetic field?

Hall measurements are made on a p-type semiconductor bar 500 u,m wide and
20 u,m thick. The Hall contacts A and B are displaced 2 p-m with respect to
each other in the direction of current flow of 3 mA. The voltage between A
and B with a magnetic field of 10 kG (lkG = 10^-5 Wb/cm2) pointing out of the
plane of the sample is 3.2 mV. When the magnetic field direction is reversed the
voltage changes to - 2 .8 mV. What is the hole concentration and mobility?
A 2.85 mm thick quartz piezoelectric crystal having a voltage sensitivity of 0.075Vm/N is subjected to a pressure of 2.6MN/ msquare. If the
permittivity of the crystal is 40.6*10E-12F/m, what amount of output voltage will be generated corresponding to the applied pressure? What will be
the charge sensitivity of the crystal? How variation in thickness will affect the voltage generated?
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:
