Abstract
Layers are produced, where the layers include a first layer formed of a metal and a second layer formed of an organic compound, the metal and the organic compound entering into an interaction, so that the layer serves as an electroactive layer for nonvolatile memories, the metal layer being deposited onto a substrate and, if appropriate, patterned, then being coated with an organic compound and being treated with a second organic compound.
Claims17
A method for producing charge transfer layers comprising a first layer formed of a metal and a second layer formed of a first organic compound, wherein the metal and the first organic compound form a charge transfer complex that serves as an electroactive layer in a nonvolatile memory, the method comprising:
- depositing a metal layer onto a substrate;
- coating the metal layer with the first organic compound;
- and
- treating the metal layer coated with the first organic compound with a vapor comprising a second organic compound.
The method of 11, wherein the organic solvent includes a nitrile group.
The method of 1, wherein the second organic compound comprises an organic solvent mixture including acetonitrile.
A method of producing charge transfer layers, the charge transfer layers comprising a first layer formed of a metal and a second layer formed of a first organic compound such that the metal and the first organic compound form a charge transfer complex, the charge transfer complex serving as an electroactive layer in a nonvolatile memory, the method comprising:
- depositing a metal layer onto a substrate;
- coating the metal layer with the first organic compound by vapor deposition of the organic compound onto the metal layer;
- and
- treating the metal layer coated with the first organic compound with a vapor of a second organic compound comprising a solvent including a nitrile group.
A charge transfer layer formed on a substrate by depositing a metal layer on the substrate and coating the metal layer with a first organic compound by vapor deposition of the organic compound onto the metal layer, and then treating the metal layer coated with the first organic compound with a vapor comprising a second organic compound, wherein the second organic compound comprises a nitrile group.
