100 GHz Transistors from Wafer Scale Epitaxial Graphene
Yu-Ming Lin, Christos Dimitrakopoulos, Keith A. Jenkins +4
High-performance graphene field-effect transistors have been fabricated on epitaxial graphene synthesized on a two-inch SiC wafer, achieving a cutoff frequency of 100 GHz for a gat…
Wafer-scale Epitaxial Graphene Growth on the Si-face of Hexagonal SiC (0001) for High Frequency Transistors
Christos Dimitrakopoulos, Yu-Ming Lin, Alfred Grill +12
Up to two layers of epitaxial graphene have been grown on the Si-face of two-inch SiC wafers exhibiting room-temperature Hall mobilities up to 1800 cm^2/Vs, measured from ungated,…
Multi-carrier Transport in Epitaxial Multi-layer Graphene
Yu-Ming Lin, Christos Dimitrakopoulos, Damon B. Farmer +9
Variable-field Hall measurements were performed on epitaxial graphene grown on Si-face and C-face SiC. The carrier transport involves essentially a single-type of carrier in few-la…
Multilayer epitaxial graphene formed by pyrolysis of polycrystalline silicon-carbide grown on c-plane sapphire substrates
Timothy J. McArdle, Jack O. Chu, Yu Zhu +6
We use ultra-high vacuum chemical vapor deposition to grow polycrystalline silicon carbide (SiC) on c-plane sapphire wafers which are then annealed between 1250 and 1450°C in vacu…
