Claim 1
Independent Claim
131 words
IN A METHOD OF FABRICATING RADIATION SENSITIVE CRYSTAL ASSEMBLIES, THE STEPS OF OBTAINING A BODY OF CRYSTALLINE STRUCTURE WHICH IS SENSITIVE TO RADIATION WITHIN DESIRED WAVE BANDS, MECHANICALLY SUPPORTING A METALLIC ELECTRODE IN CONTACT WITH A SURFACE OF THE CRYSTALLINE STRUCTURE, CONNECTING SAID ELECTRODE AND CRYSTALLINE STRUCTURE IN SERIES ELECTRICAL CIRCUIT WITH A SOURCE OF D.C. VOLTAGE WITH THE ELECTRODE CONNECTED TO THE POSITIVE SIDE OF THE CIRCUIT AND THE CRYSTALLINE STRUCTURE THE NEGATIVE SIDE TO APPLY A SUBSTANTIAL VOLTAGE PULSE HAVING SUFFICIENT AMPLITUDE TO BREAK DOWN ANY DIODIC SURFACE BARRIER ON THE CRYSTALLINE STRUCTURE THAT MAY BE PRESENT BETWEEN THE ELECTRODE AND CRYTALLINE STRUCTURE BUT INSUFFICIENT TO DESTROY THE CRYSTALLINE STRUCTURE ADJACENT THE JUNCTION OF THE ELECTRODE AND THE CRYSTALLINE STRUCTURE TO PROVIDE A PURE CHIMC CONNECTION BETWEEN THE TWO.
