| 英文摘要 |
In this report printed thin film transistors and logic circuits on flexible
substrates are reported. The top-gate thin film transistors were made of the sorted
semiconducting single-walled carbon nanotubes (sc-SWCNTs) ink as channel material
and printed silver lines as top electrodes and interconnect. 5 nm HfOx thin films
pre-deposited on PET substrates by atomic layer deposition (ALD) act as the adhesion
layers to significantly improve the immobilization efficiency of sc-SWCNTs and
environmental stability. The immobilization mechanism was investigated in detail.
The flexible partially-printed top-gate SWCNT TFTs display ambipolar characteristics
with slightly strong p-type when using 50 nm HfOx thin films as dielectric layer, as
well as the encapsulation layer by atomic layer deposition (ALD) at 120 degrees C.
The hole mobility, on/off ratio and subthreshold swing (SS) are similar to 46.2 cm
(2) V-1 s(-1), 10(5) and 109 mV per decade, respectively. Furthermore, partially-
printed TFTs show small hysteresis, low operating voltage (2 V) and high stability
in air. Flexible partially-printed inverters show good performance with voltage gain
up to 33 with 1.25 V supply voltage, and can work at 10 kHz. The frequency of
flexible partially-printed five-stage ring oscillators can reach 1.7 kHz at supply
voltages of 2 V with per stage delay times of 58.8 mu s. This work paves a way to
achieve printed SWCNT advanced logic circuits and systems on flexible substrates. |
