Programmable Volatile Memory Devices of Nitrogen-Linked Poly(2,7-carbazole)s : Polymer Devices and Analysis of Devices Structure Using X-Ray Reflectivity |
| 초록 |
The programmable volatile memory devices of the following nitrogen-linked poly(2,7-carbazole)s: These polymers are amorphous; however, in thin films, they are slightly oriented in the film plane. All polymers in devices with aluminum top and bottom electrodes were found to exhibit similar DRAM behaviors without polarity. They are operable with a low voltage (less than (3 V) and a high ON/OFF current ratio (105-109, depending on the polymer) over the thickness range 8-60 nm. The memory behaviors were found to be governed by space-charge limited conduction and local filament formation. These memory characteristics might originate from the electrondonating carbazole and triphenylamino units in the polymer backbones, which act as charge-trapping sites but have weak electric polarization because of the absence of counterparts. Overall, these polymers are suitable active materials for the mass production at low cost of high-performance, programmable volatile memory devices. |
