-The energy gap is about 1 eV for a semi-conductor and about 6 eV for an Insulator.  In a Conductor, there is no energy gap.  The Valence and Conduction bands overlap.
+The energy gap in a semi-conductor is about 1 eV at room temperature.  This gap is so small that valence electrons could enter the conductive band due to their thermal excitation.
 Silcon is the most commonly used material for such detectors.  Germanium, Gallium-Arsenide, and diamond are also used.
