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...

Gehring P, Sowa JK, Cremers J, Wu Q, Sadeghi H, Sheng Y, Warner JH, Lambert CJ, Briggs GAD, Mol JA.
PMID: 28423272
ACS Nano. 2017 Jun 27;11(6):5325-5331. doi: 10.1021/acsnano.7b00570. Epub 2017 Apr 21.

Graphene provides a two-dimensional platform for contacting individual molecules, which enables transport spectroscopy of molecular orbital, spin, and vibrational states. Here we report single-electron tunneling through a molecule that has been anchored to two graphene leads. Quantum interference within...
