The Influence of Defects Produced by High Energy Electrons on the Electrical Characteristics of p-n Junctions; INFLUENCE DES DEFAUTS CREES PAR DES ELECTRONS DE GRANDE ENERGIE SUR LES CARACTERISTIQUES ELECTRIQUES DES JONCTIONS P-N
The life-time of minority carriers in semiconductors is very sensitive to the presence of defects introduced by high-energy electrons. The formation of defects thus affects the short-circuiting current and the open circuit voltage of a p-n junction, these being dependent on the lifetime. Several types of germanium and silicon junctions were bombarded with 2-Mev electrons from a Van de Graaf and with beta -particles from radioactive sources. The experiments were carried out both at ordinary temperatures and that of liquid air. In this latter case an anomaly in the electron-volt effect was found: the short-circuiting current and the voltage in vacuo, after an initial decrease, increased again and exceeded their initial maximum value before once more decreasing. A qualitative interpretation of this abnormal effect is given. (auth)
