Atomic resolution imaging of graphene by transmission electron microscopy.

Nanoscale

Robertson AW, Warner JH.
PMID: 23595204
Nanoscale. 2013 May 21;5(10):4079-93. doi: 10.1039/c3nr00934c.

The atomic structure of a material influences its electronic, chemical, magnetic and mechanical properties. Characterising carbon nanomaterials, such as fullerenes, nanotubes and graphene, at the atomic level is challenging due to their chemical reactivity and low atomic mass. Transmission...

Atomic Level Distributed Strain within Graphene Divacancies from Bond Rotations.

ACS nano

Chen Q, Robertson AW, He K, Gong C, Yoon E, Lee GD, Warner JH.
PMID: 26204434
ACS Nano. 2015 Aug 25;9(8):8599-608. doi: 10.1021/acsnano.5b03801. Epub 2015 Jul 23.

Vacancy defects play an important role in influencing the properties of graphene, and understanding their detailed atomic structure is crucial for developing accurate models to predict their impact. Divacancies (DVs) are one of the most common defects in graphene...

Low-Temperature Chemical Vapor Deposition Synthesis of Pt-Co Alloyed Nanoparticles with Enhanced Oxygen Reduction Reaction Catalysis.

Advanced materials (Deerfield Beach, Fla.)

Adv Mater. 2016 Sep;28(33):7115-22. doi: 10.1002/adma.201600469. Epub 2016 Jun 08.

Novel Pt-Co alloyed nanocatalysts are generated via chemical vapor deposition-assisted facile one-pot synthesis. The method guarantees highly monodisperse Pt-Co alloy nanoparticles with precise control of metallic compositions within 1 at%. A significant features is that a perfectly alloyed single-crystal...

Atomic structure and dynamics of metal dopant pairs in graphene.

Nano letters

He Z, He K, Robertson AW, Kirkland AI, Kim D, Ihm J, Yoon E, Lee GD, Warner JH.
PMID: 24945707
Nano Lett. 2014 Jul 09;14(7):3766-72. doi: 10.1021/nl500682j. Epub 2014 Jun 19.

We present an atomic resolution structural study of covalently bonded dopant pairs in the lattice of monolayer graphene. Two iron (Fe) metal atoms that are covalently bonded within the graphene lattice are observed and their interaction with each other...

Elongated Silicon-Carbon Bonds at Graphene Edges.

ACS nano

Chen Q, Robertson AW, He K, Gong C, Yoon E, Kirkland AI, Lee GD, Warner JH.

ACS Nano. 2016 Jan 26;10(1):142-9. doi: 10.1021/acsnano.5b06050. Epub 2015 Nov 30.

We study the bond lengths of silicon (Si) atoms attached to both armchair and zigzag edges using aberration corrected transmission electron microscopy with monochromation of the electron beam. An in situ heating holder is used to perform imaging of...

Growth of Continuous Monolayer Graphene with Millimeter-sized Domains Using Industrially Safe Conditions.

We show that dislocations located at the edge of graphene cause different lattice deformations to those located in the bulk lattice. When a dislocation is located near an edge, a decrease in the rippling and increase of the in-plane...
