Abstract
Disclosed herein are an organic memory device and a method for fabricating the device. The organic memory device may include a first electrode, a second electrode and an organic active layer wherein the organic active layer includes an upper organic material layer formed of an electrically conductive organic material containing heteroatoms and a lower organic material layer formed of an electrically non-conductive organic material containing heteroatoms. Because the organic memory device exhibits improved thermal stability and non-volatility, it may be well suited for use in nonvolatile large-capacity storage units. Flexible electrodes may be used in the organic memory device to fabricate flexible memory devices.
Claims22
An organic memory device comprising a first electrode, a second electrode and an organic active layer, wherein the organic active layer includes an upper organic material layer formed of an electrically conductive organic material containing heteroatoms and a lower organic material layer formed of an electrically non-conductive organic material containing heteroatoms and further wherein the organic active layer includes metal ions that may be coordinated with the heteroatoms in the upper and lower organic material layers.
A method for fabricating an organic memory device comprising:
- forming a first electrode;
- forming a second electrode;
- forming an organic active layer extending between the first and second electrodes, wherein forming the organic active layer includes forming a lower organic material layer that includes an electrically non-conductive organic material containing heteroatoms on a substrate and forming an upper organic material layer that includes an electrically conductive organic material containing heteroatoms on the lower organic material layer;
- and
- providing metal ions in the upper and lower organic material layers under conditions whereby the metal ions become linked to the heteroatoms.
