To solve the problem of finding the number of holes in a pure semiconductor sample, we can follow these steps: ### Step 1: Understand the relationship between conduction electrons and holes In a pure semiconductor, the number of conduction electrons is equal to the number of holes. This means that if we know the number of conduction electrons, we can directly conclude that the number of holes is the same. ### Step 2: Identify the given data We are given: - The number of conduction electrons = \(6 \times 10^{19}\) per cubic meter. ...
