Large area uniform nanocrystalline graphene is grown by chemical vapor deposition on arbitrary insulating substrates that can survive ∼1000 °C. The as-synthesized graphene is nanocrystalline with a domain size in the order of ∼10 nm. The material possesses a transparency and conductivity similar to standard graphene fabricated by exfoliation or catalysis. A noncatalytic mechanism is proposed to explain...
This letter presents a detailed study of transport in graphene field-effect transistors (GFETs) with various channel lengths, from 5 μm down to 90 nm, using transferred graphene grown by chemical vapor deposition. An electron-hole asymmetry observed in short-channel devices suggests a strong impact from graphene/metal contacts. In addition, for the first time, we observe a shift of the gate voltage...
Owing in part to complementary metal-oxide-semiconductor (CMOS) scaling issues, the semiconductor industry is placing an increased emphasis on emerging materials and devices that may provide a solution beyond the 22-nm node. Single and few layers of carbon sheets (graphene) have been fabricated by a variety of techniques including mechanical exfoliation and chemical vapor deposition, and field-effect...
Graphene is a possible candidate for advanced channel materials in future field effect transistors. This presentation gives a brief overview about recent experimental results in the field of graphene transistors for future electronic applications.
