Researchers at MIT are studying the fractional quantum Hall effect, which expands the classical Hall effect to mesoscopic length scales. Which of the following statements is NOT true about the classical Hall effect?
W) The Hall voltage is directly proportional to the strength of the applied magnetic field
X) A Hall effect sensor can not differentiate between n-type and p-type semiconductors
Y) The Hall voltage pushes charge carriers perpendicular to the magnetic field
Z) Current carrying electrons and holes are deflected to opposite sides of the plate
✔️Answer:X) A Hall effect sensor can not differentiate between n-type and p-type semiconductors
