Journal ArticleDOI
Nucleation of Epitaxial Graphene on SiC(0001)
Joshua A. Robinson,Xiaojun Weng,Kathleen A. Trumbull,Randall Cavalero,Maxwell Wetherington,Eric Frantz,Michael LaBella,Zachary Hughes,Mark A. Fanton,David Snyder +9 more
TL;DR: This work provides the first direct evidence that nucleation of epitaxial graphene on silicon carbide occurs along the (110n) plane and shows that the nucleated graphene quality improves as the synthesis temperature is increased.
Journal ArticleDOI
Characterization of Graphene Films and Transistors Grown on Sapphire by Metal-Free Chemical Vapor Deposition
Mark A. Fanton,Joshua A. Robinson,Conor Puls,Ying Liu,Matthew J. Hollander,B.E. Weiland,Michael LaBella,Kathleen A. Trumbull,Richard Kasarda,Casey A. Howsare,J.P. Stitt,David W. Snyder +11 more
TL;DR: A novel method for the direct metal-free growth of graphene on sapphire that yields high quality films comparable to that of graphene grown on SiC by sublimation is presented.
Journal ArticleDOI
Epitaxial graphene transistors: Enhancing performance via hydrogen intercalation
Joshua A. Robinson,Matthew J. Hollander,Michael LaBella,Kathleen A. Trumbull,Randall Cavalero,David W. Snyder +5 more
TL;DR: The importance of buffer elimination at the graphene/SiC(0001) interface for high frequency applications is demonstrated and a 10× improvement in the extrinsic current gain response of graphene transistors with optimal extrinsics current-gain cutoff frequencies of 24 GHz is reported.
Journal ArticleDOI
Integration of hexagonal boron nitride with quasi-freestanding epitaxial graphene: toward wafer-scale, high-performance devices.
Michael S. Bresnehan,Matthew J. Hollander,Maxwell Wetherington,Michael LaBella,Kathleen A. Trumbull,Randal Cavalero,David W. Snyder,Joshua A. Robinson +7 more
TL;DR: Temperature dependent Hall measurements indicate little contribution from remote surface optical phonon scattering and suggest that, compared to HfO(2) based dielectrics, h-BN can be an excellent material for preserving electrical transport properties.
Journal ArticleDOI
Epitaxial graphene materials integration: effects of dielectric overlayers on structural and electronic properties.
Joshua A. Robinson,Michael LaBella,Kathleen A. Trumbull,Xiaojun Weng,Randall Cavelero,Tad Daniels,Zachary Hughes,Mathew Hollander,Mark A. Fanton,David W. Snyder +9 more
TL;DR: Graphene quality degrades most severely following deposition of Ta( 2)O(5), while the deposition if TiO(2) appears to improve the graphene carrier mobility.
