How Is the Junction Barrier Between N-Type and P-Type Silicon

question 35

Multiple Choice

How is the junction barrier between n-type and p-type silicon much like a one-way valve?

• A)The electrons can only be lost from the p-type silicon wafer.
• B)The orientation of the charge around the barrier allows the electrons to flow in only one direction.
• C)The electrons can only be lost from the n-type silicon wafer.
• D)Only one side of the barrier is exposed to light, which causes the electrons to flow in the opposite direction.
