Abstract
It is observed that the barrier height in Al‐(Al‐oxide)‐Al sandwiches is a strong function of the Al‐oxide thickness; it is also a strong function of the illumination, particularly at low temperatures. These results offer conclusive evidence that the effect is due to space charge trapped in the Al‐oxide.Keywords
