Journal ArticleDOI
Control and characterization of individual grains and grain boundaries in graphene grown by chemical vapour deposition
Qingkai Yu,Qingkai Yu,Luis A. Jauregui,Wei Wu,Robert Colby,Jifa Tian,Zhihua Su,Helin Cao,Zhihong Liu,Deepak Pandey,Dongguang Wei,Ting-Fung Chung,Peng Peng,Nathan P. Guisinger,Eric A. Stach,Eric A. Stach,Jiming Bao,Shin-Shem Pei,Yong P. Chen +18 more
TL;DR: It is shown that grain boundaries give a significant Raman 'D' peak, impede electrical transport, and induce prominent weak localization indicative of intervalley scattering in graphene, opening a route towards scalable fabrication of single-crystal graphene devices without grain boundaries.

Control and Characterization of Individual Grains and Grain Boundaries in Graphene Grown by Chemical Vapor Deposition
Qingkai Yu,Luis A. Jauregui,Wei Wu,Robert Colby,Jifa Tian,Zhihua Su,Helin Cao,Zhihong Liu,Deepak Pandey,Dongguang Wei,Ting-Fung Chung,Peng Peng,Nathan P. Guisinger,Eric A. Stach,Jiming Bao,Shin-Shem Pei,Yong P. Chen +16 more
TL;DR: In this paper, single-crystal graphene grains synthesized by ambient CVD on polycrystalline Cu are studied and individual boundaries between coalescing grains affect graphene's electronic properties.
Journal ArticleDOI
Graphene segregated on Ni surfaces and transferred to insulators
TL;DR: In this paper, surface segregation and substrate transfer were used to synthesize high quality graphene by dissolving carbon in Ni at high temperatures followed by cooling down with various rates, which led to different segregation behaviors, strongly affecting the thickness and quality of the graphene films.
Journal ArticleDOI
Thermal conductivity and thermal rectification in graphene nanoribbons: a molecular dynamics study.
TL;DR: In this article, the thermal conductivity of symmetric and asymmetric graphene nanoribbons (GNRs) of several nanometers in size (up to ∼4 nm wide and ∼10 nm long) was calculated.
Journal ArticleDOI
Polycrystalline graphene and other two-dimensional materials.
Oleg V. Yazyev,Yong P. Chen +1 more
TL;DR: A review of the large body of research reported in the past few years on polycrystalline graphene, which discusses its growth and formation, the microscopic structure of grain boundaries and their relations to other types of topological defect such as dislocations.
