David Le Bretont—as mainly observed by .—also at the boundary between two semiconductors. These zones, the conductivity of which differs from the interior of the semiconductor, are generally situated on both sides of the boundary. Therefore, this layer is called “Doppelrandschicht” (double-barrier layer) in contra
