Jie Jiang,Xin Sun,Xinchun Chen,Baiwei Wang,Zhizhong Chen,Yang Hu,Yuwei Guo,Lifu Zhang,Yuan Ma,Lei Gao,Fengshan Zheng,Lei Jin,Min Chen,Zhiwei Ma,Yuanyuan Zhou,Nitin P. Padture,Kory Beach,Humberto Terrones,Yunfeng Shi,Daniel Gall,Toh-Ming Lu,Esther Wertz,Jing Feng,Jian Shi +23 more
TL;DR: Remote epitaxial perovskite films are synthesized using polar substrates coated with graphene with density-controlled dislocations and confirmed to have negative impact on carrier dynamics, providing an avenue to develop free-standing halide perovkite film with low dislocation density and improved carried dynamics.

Effect of domain boundaries on the Raman spectra of mechanically strained graphene.
TL;DR: It is found that under strain the Raman spectra of CVD graphene transferred onto a silicone elastomer exhibits unusual behavior, with the G and 2D band frequencies decreasing and increasing respectively with applied strain.

Neil R. Wilson,Alexander J. Marsden,Mohammed Saghir,Catherine J. Bromley,Renald Schaub,Giovanni Costantini,Thomas W. White,Cerianne Partridge,Alexei Barinov,Pavel Dudin,Ana M. Sanchez,James J. Mudd,Marc Walker,Gavin R. Bell +13 more
TL;DR: In this paper, an epitaxial relationship between graphene and copper foils was found, and two preferred orientations of graphene were found, ±8° from the Cu[010] direction, creating a non-uniform distribution of graphene grain boundary misorientation angles.

Reversible Loss of Bernal Stacking during the Deformation of Few-Layer Graphene in Nanocomposites
Lei Gong,Robert J. Young,Ian A. Kinloch,Sarah J. Haigh,Jamie H. Warner,Jonathan A. Hinks,Ziwei Xu,Li Li,Feng Ding,Ibtsam Riaz,Rashid Jalil,Kostya S. Novoselov +11 more
TL;DR: It has been demonstrated that band broadening takes place during tensile deformation for mono- and bilayer graphene but that band narrowing occurs when the number of graphene layers is more than two and that this change in Raman band shape and width has been interpreted as being due to a reversible loss of Bernal stacking during deformation.

Electric Field Effect in Atomically Thin Carbon Films
Kostya S. Novoselov,Andre K. Geim,Sergey V. Morozov,Da Jiang,Y. Zhang,S. V. Dubonos,Irina V. Grigorieva,A. A. Firsov +7 more
TL;DR: Monocrystalline graphitic films are found to be a two-dimensional semimetal with a tiny overlap between valence and conductance bands and they exhibit a strong ambipolar electric field effect.

TL;DR: This study reports an experimental study of a condensed-matter system (graphene, a single atomic layer of carbon) in which electron transport is essentially governed by Dirac's (relativistic) equation and reveals a variety of unusual phenomena that are characteristic of two-dimensional Dirac fermions.

TL;DR: This work shows that graphene's electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers, and allows unambiguous, high-throughput, nondestructive identification of graphene layers, which is critically lacking in this emerging research area.

Interpretation of Raman spectra of disordered and amorphous carbon
Andrea C. Ferrari,John Robertson +1 more
TL;DR: In this paper, a model and theoretical understanding of the Raman spectra in disordered and amorphous carbon is given, and the nature of the G and D vibration modes in graphite is analyzed in terms of the resonant excitation of \ensuremath{\pi} states and the long-range polarizability of the long range bonding.
