Hybrid CuO/SnO2 nanocomposites are synthesized by a facile thermal annealing method on Cu foils. Compared to pristine CuO and SnO2 nanostructures, hybrid CuO/SnO2 nanocomposites exhibit the enhanced electrochemical performances as the anode material of lithium ion batteries (LIBs) with high specific capacity and excellent rate capability. The binder free CuO/SnO2 nanocomposites deliver a specific capacity of 718 mA h g−1 at a current density of 500 mA g−1 even after 200 cycles. The enhanced electrochemical performances are attributed to the synergistic effect between SnO2 nanoparticles and CuO nanoarchitectures. Such hybrid CuO/SnO2 nanocomposites could open up a new route for the development of next-generation high-performance and cost-effective binder free anode material of LIBs for mass production.
In this paper, a hybrid CMOS inverter employing In-Ga-Zn oxide (IGZO) (inorganic, n-channel) and P3HT (organic, pchannel) thin film transistors (TFTs) is reported. Both inorganic and organic TFTs are fabricated by ink-jet printing technology. The field effect mobility of p and n channel TFTs are 0.0038 and 0.27 cm 2 /V s, respectively. The inverter exhibited an obvious inverter response for switching between logic '1' and logic '0', and yielded a high gain of 14 at V DD = 30 V. With the combining advantages of oxide semiconductor (n-type, high mobility) and organic (commonly ptype), it is promising to construct powerful functional CMOS circuits, such as ring oscillator and shift registers.
