Chapter 19: Problem 2648

The flow of valence electrons to the left means that holes are flowing. (A) Left (B) Right (C) Either way (D) None

Short Answer

Expert verified
The flow of holes is in the opposite direction of the flow of valence electrons. Given that the valence electrons are flowing towards the left, the correct answer is (B) Right, which indicates that holes are flowing towards the right.

Step by step solution

01

Understand the relationship between the flow of valence electrons and holes

In a semiconductor material, valence electrons move from the valence band to the conduction band, leaving holes behind in the valence band. These holes represent the absence of an electron in the valence band. The flow of holes is in the opposite direction of the flow of valence electrons.
02

Determine the direction of hole flow

Given that the flow of valence electrons is to the left, the flow of holes will be in the opposite direction, which is to the right.
03

Select the correct answer

Since the holes are flowing to the right, the correct answer is: (B) Right
