Questions and Answers

Why are many conventional methods for measuring resistivity unsatisfactory for semiconductors?

They cannot measure the conductivity of semiconductor ingots or slices

Metal-semiconductor contacts are usually rectifying in nature (correct)

They inject excess concentration of minority carriers

They do not permit measurements of resistivity in samples of various shapes

What is the primary advantage of the four probe method for measuring resistivity in semiconductors?

It eliminates the injection of minority carriers by current carrying contacts

It overcomes the rectifying nature of metal-semiconductor contacts (correct)

It allows measurements of resistivity in samples of various shapes

It accurately measures the conductivity of semiconductor ingots or slices

What does the four probe method allow measurements of, in samples of various shapes?
