Journal ArticleDOI
Role of Kinetic Factors in Chemical Vapor Deposition Synthesis of Uniform Large Area Graphene Using Copper Catalyst
TL;DR: Interestingly, graphene syntheses using a Cu catalyst in APCVD processes at higher methane concentrations revealed that the growth is not self-limiting, which is in contrast to previous observations for the LPCVD case.
Journal ArticleDOI
Growth of large-area single- and Bi-layer graphene by controlled carbon precipitation on polycrystalline Ni surfaces
Alfonso Reina,Stefan Thiele,Xiaoting Jia,Sreekar Bhaviripudi,Mildred S. Dresselhaus,Juergen A. Schaefer,Jing Kong +6 more
TL;DR: In this article, the surface of polycrystalline Ni thin films during atmospheric chemical vapor deposition (CVD) is controlled by controlling both the methane concentration during CVD and the substrate cooling rate during graphene growth to improve the thickness uniformity.
Journal ArticleDOI
Selective Molecular Transport through Intrinsic Defects in a Single Layer of CVD Graphene
Sean C. O'Hern,Cameron A. Stewart,Michael S. H. Boutilier,Juan Carlos Idrobo,Sreekar Bhaviripudi,Sarit K. Das,Jing Kong,Tahar Laoui,Muataz Ali Atieh,Rohit Karnik +9 more
TL;DR: Graphene composite membranes with nominal areas more than 25 mm fabricated by transfer of a single layer of CVD graphene onto a porous polycarbonate substrate are reported, presenting the first step toward the realization of practical membranes that use graphene as the selective material.
Journal ArticleDOI
CVD Synthesis of Single-Walled Carbon Nanotubes from Gold Nanoparticle Catalysts
Sreekar Bhaviripudi,Ervin Mile,Stephen A. Steiner,Aurea Tucay Zare,Mildred S. Dresselhaus,and Angela M. Belcher,Jing Kong +6 more
TL;DR: The first demonstration of the synthesis of single-walled carbon nanotubes using gold nanoparticle catalysts with thermal chemical vapor deposition is presented, characterized by atomic force microscopy and resonant Raman spectroscopy.
Journal ArticleDOI
Topographic and Spectroscopic Characterization of Electronic Edge States in CVD Grown Graphene Nanoribbons
Minghu Pan,E. Costa Girão,E. Costa Girão,Xiaoting Jia,Sreekar Bhaviripudi,Qing Li,Jing Kong,Vincent Meunier,Mildred S. Dresselhaus +8 more
TL;DR: Using scanning tunneling microscopy and spectroscopy techniques, a pristine structure was ruled out in favor of a reconstructed edge structure composed of 5-7 member rings, showing a better match with experimental results, and thereby suggesting the possibility of a defective morphology at the edge of CVD grown nanoribbons.
