Findings on Fullerenes Detailed by Investigators at University of California (Large-scale complementary macroelectronics using hybrid integration of carbon nanotubes and IGZO thin-film transistors)

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Fullerenes have been published. According to news originating from Los Angeles, California, by NewsRx correspondents, research stated, "Carbon nanotubes and metal oxide semiconductors have emerged as important materials for p-type and n-type thin-film transistors, respectively; however, realizing sophisticated macroelectronics operating in complementary mode has been challenging due to the difficulty in making n-type carbon nanotube transistors and p-type metal oxide transistors."

Our news journalists obtained a quote from the research from the University of California, "Here we report a hybrid integration of p-type carbon nanotube and n-type indium-gallium-zinc- oxide thin-film transistors to achieve large-scale (>1,000 transistors for 501-stage ring oscillators) complementary macroelectronic circuits on both rigid and flexible substrates. This approach of hybrid integration allows us to combine the strength of p-type carbon nanotube and n-type indium-gallium-zinc-oxide thin-film transistors, and offers high device yield and low device variation."

According to the news editors, the research concluded: "Based on this approach, we report the successful demonstration of various logic gates (inverter, NAND and NOR gates), ring oscillators (from 51 stages to 501 stages) and dynamic logic circuits (dynamic inverter, NAND and NOR gates)."
