| Research Abstract |
It was clarified by using the air-free system that the origin of the instability of the n-type properties of the CNTTFTs with Al contacts in air was not due to the oxidation of the Al but due to the oxygen absorption on the device surfaces. The ambipolar CNTFETs with graphitic carbon contacts were changed to the n- and p-type devices by forming the metal overlayers with different work functions on the side surface of the CNT channel. The ring oscillator fabricated on the flexible plastic substrate by the transfer technique of CNT network using poly vinyl alcohol exhibited a delay time of 1.1 us/gate. In addition, the successful operation of the flexible CNTTFT medium-scale integrated circuits with 108 circuit elements was also confirmed.
