Electrons passing through a flat semiconductor strip (lying in the x-y plane) carry a current of 40 mA in the y-direction. If a magnetic field of 0.1 Tesla is applied in the z-direction (i.e. perpendicular to the strip) and the number of electrons per unit area is 2×1012 cm-2, what is the (Hall) voltage measured across the device in the x-direction?

Problem 6. A flat strip of metal is located in the z - y plane. It extends infinitely in the ±y-directions, and from x =-0.01 to x = +0.01. It carries a total current of 50A in the +y-direction, distributed over the width so that the surface current density is 2500 A/m.

Inside your smartphone is a small integrated circuit called a "Hall sensor" that measures the magnetic field to fairly high precision. (It is actually made of three separate "Hal bars", to measure the field components in the r, y, and z directions). The Hall sensor acts like a compass for your phone, and assists in navigation and GPS apps. Let's assume each Hall bar is a strip that is 20 11m long, 5 ㎛ wide, and 1 μm thick. (a)...
