A METHOD OF IMPROVING THE ELECTRICAL PROPERTIES OF A THIN FILM STRUCTURE COMPRISING A FIRST ELECTRODE OF NOIBIUM, A FILM OF NOIBUIL PENTOXIDE ON SAID NOBIUM ELECTRODE, AND A SECOND ELECTRODE OF BISMUTH, SAID PENTOXIDE FILM HAVING A THICKNESS IN THE RANGE OF 200 TO 3000 ANGSTROMS AND BEING POSITIONED BETWEEN AND IN CONTACT WITH SAID FIRST AND SECOND ELECTRODES, WHICH METHOD COMPRISES IMPRESSING A FIRST VOLTAGE POTENTIAL ACROSS SAID FILM OF NIOBIUM OXIDE FOR A FIRST PERIOD OF TIME, SAID FIRST VOLTAGE POTENTIAL AND SAID FIRST PERIOD OF TIME BEING SUFFICIENT TO EFFECT A MARKED INCREASE IN THE CURRENT FLOWING ACROSS SAID OXIDE FILM AT THE END OF THE SAID FIRST TIME PERIOD AS COMPARED WITH THE CURRENT FLOWING ACROSS SAID OXIDE FILM AT THE BEGINNING OF SAID FIRST TIME PERIOD, THE CURRENT FLOWING ACROSS THE SAID OXIDE FILM AT THE END OF SAID FIRST TIME PERIOD BEING LESS THAN ABOUT 10 MILLIAMPERES, AND THEREAFTER IMPRESSING A SECOND VOLTAGE POTENTIAL LESS THAN SAID FIRST VOLTAGE POTENTIAL ACROSS SAID FILM OF NOIBIUM OXIDE FOR A SECOND PERIOD OF TIME, SAID SECOND VOLTAGE POTENTIAL AND SAID SECOND PERIOD OF TIME BEING SUFFICIENT TO EFFECT A MARKED INCREASE IN THE CONDUCTANCE OF THE SAID OXIDE FILM AT THE END OF SAID SECOND TIME PERIOD AS COMPARED WITH THE CONDUCTANCE OF THE SAID OXIDE FILM AT THE BEGINNING OF SAID SECOND PERIOD OF TIME, THE CURRENT FLOWING ACROSS SAID OXIDE FILM AT THE END OF SAID SECOND PERIOD OF TIME BEING LESS THAN ABOUT 10 MILLIAMPERES.
