Claim 1
Independent Claim
127 words
AN ELECTRICAL TRANSLATING DEVICE COMPRISING A BODY OF CRYSTALLINE MATERIAL HAVING FIRST AND SECOND OPPOSED FACES, SAID BODY HAVING A LOW DENSITY OF TRAPPING STATES, THE RATIO OF TRAP DENSITY TO THE RELATIVE PERMITITIVITY OF SAID MATERIAL BEING LESS THAN **12, A FIRST ELECTRODE IN CONTACT WITH SAID FIRST FACE, A SECOND ELECTRODE, SAID SECOND ELECTRODE BEING DISPOSED WITH RESPECT TO SAID FIRST ELECTRODE TO ALLOW THE FLOW OF A SPACE-CHARGE-LIMITED CURRENT OF INJECTED CHARGE CARRIERS THROUGH SAID BODY IN THE PRESENCE OF A SUFFICIENT DIFFERENCE OF POTENTIAL BETWEEN SAID FIRST AND SECOND ELECTRODES, AND A THIRD ELECTRODE IN NON-OHMIC CONTACT WITH SAID BODY, SAID THIRD ELECTRODE BEING ADAPTED FOR THE APPLICATION OF A POTENTIAL THERETO TO CONTROL THE FLOW OF SAID SPACE-CHARGE-LIMITED CURRENT THROUGH SAID BODY.
