Selbstpolung bei Perowskiten vom Typ ABO¶3¶ |
摘要 |
A process for producing a ferroelectric perovskite of ABO3 type, with macroscopically oriented, permanent internal electric fields in the surface region, involves exposing the perovskite to an oxidising atmosphere until the accumulated charge, on para-electric to ferroelectric phase transformation, is reproducibly equal to the depolarised charge on ferroelectric to para-electric phase transformation. |
