Physics education research, electronic materials, and the musings of Christopher Moore, Ph.D.

Here's the question:  Thermal energy can shift some of the electrons in a hot semiconductor from valence levels to conduction levels. What effect do these shifts have on the semiconductor’s ability to conduct electricity?

Here's my attempt at an explanation:  The electrons release a ton of energy and because of the electron movement, the semiconductor can conduct more electricity.

Is this correct?  Is my explanation flawed in any way(s)?
