<p>
= energy gap;</p>
<p>
energy diff in electron volts btwn the top of the valence band and
the bottom of the conduction band in semiconductors.</p>
<p>
energy required to free an outer shell electron from its orbit to become a mobile charge carrier.</p>
<p>
large bands gaps occur in insulators</p>
<p>
those with smaller band gaps are semiconductors</p>
<p>
while conductors have small or none cuz valence and conduction bands overlap.</p>
