NONVOLATILE MEMORY ELEMENT |
摘要 |
<p>Provided is a material composition which allows the preparation of a nonvolatile memory element comprising a perovskite-type transition metal oxide having the CER effect by the use of three chemical elements. A nonvolatile memory element, which comprises an electric conductor having a shallow work function or a small electronegativity, such as Ti, as an electrode, and a rare earth-copper oxide comprising a rare earth element, copper and oxygen, such as La<SUB>2</SUB>CuO<SUB>4</SUB>, as a material constituting a heterojunction with the electric conductor.</p> |
