| 发明名称 | Switchable electronic device and method of switching said device | ||
| 摘要 | A switchable electronic device comprises a hole blocking layer and a layer comprising a conductive material between first and second electrodes, wherein the conductivity of the device may be irreversibly switched upon application of a current having a current density of less than or equal to 100 A cm−2 to a conductivity at least 100 times lower than the conductivity of the device before switching. The conductive material is a doped organic material such as doped optionally substituted poly(ethylene dioxythiophene). | ||

| 主权项 | 1. A switchable electronic device comprising a hole blocking and electron transporting layer comprising a wide bandgap semiconductor hole blocking and electron transporting material and a layer comprising a doped organic material between first and second electrodes, wherein the conductivity of the device is irreversibly switched upon application of a current having a current density of no more than 0.2 A cm−2 to a conductivity at least 100 times lower than the conductivity of the device before switching. | ||
