What will happen to a semiconductor at absolute zero?

Explanation

### Step-by-Step Solution:

1. **Understanding Absolute Zero:**
- Absolute zero is defined as 0 Kelvin or -273.16 degrees Celsius. At this temperature, all molecular motion ceases, meaning that there is no thermal energy available in the system.

2. **Behavior of Electrons in Semiconductors:**
- In a semiconductor, electrons typically occupy the valence band. For a semiconductor to conduct electricity, electrons must be able to move from the valence band to the conduction band.
