A given doped semiconductor can be identified as p or n type by:
A)measuring its electrical conductivity
B)measuring its magnetic susceptibility
C)measuring its coefficient of resistivity
D)measuring its heat capacity
E)performing a Hall effect experiment

Question

Quizplus · Accepted Answer

Performing a Hall effect experiment allows for the determination of the type of semiconductor by measuring the direction and magnitude of the current induced perpendicular to the applied electric and magnetic fields. The sign of this current reveals whether the semiconductor is p or n type. Measuring electrical conductivity, magnetic susceptibility, coefficient of resistivity, or heat capacity may provide additional information about the semiconductor, but does not directly determine its type.
