Below 240 K, an unconventional behavior is observed that is well explained on the basis of the appearance of ail intermediate band (IB) region able to form a blocking junction with the substrate and of the appearance of an IB conduction. Explanations based on ordinary device physics fail to justify all the unconventional behavior of the characteristics observed. %~
