Direct Growth of Periodic array of orgaic crystals on Polymer Gate Dielectric for Organic Electronic Device |
| 초록 |
A solution based simple approach is developed to prepare periodic arrays of large, elongated crystals of π-conjugated organic molecules (TCNQ). The ordered crystalline array is successfully used to fabricate low-voltage organic field effect transistors, phototransistors and organic complementary inverter with polymeric gate dielectric. The TCNQ based n-channel OFET exhibited very stable field-effect characteristics with low operational (2 V) and threshold voltages (＜ 0.5 V). The highest field-effect carrier mobility in the saturation region was found to be 0.03 cm2V-1s-1. For the inverter with VDD =2 V, the noise margin for low and high voltages are 1.0 V and 0.3 V, respectively. The logic threshold is 1.3 V and the maximum gain of 4 is obtained at VIN = 1.3 V. The OPT exhibits very stable n-type characteristics with a low threshold voltage (＜ 0.5 V). Photoswitching occurs within 10 ms and photosensitivity is greater than 1 mA/W at low driving voltages and low optical powers. |
