Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice. The term Graphene was coined as a combination of graphite and the suffix -ene by Hanns-Peter Boehm, who described single-layer carbon foils in 1962. Graphene is most easily visualized as an atomic-scale chicken wire made of carbon atoms and their bonds. The crystalline or "flake" form of graphite consists of many graphene sheets stacked together.

Atomistic Green’s Functions: The Beauty of Self-energies
28 Oct 2020 | | Contributor(s):: Tillmann Christoph Kubis
This presentation gives an introduction to NEGF. It will be explained how self-energies cause NEGF to fundamentally differ from most other quantum methods. Atomistic examples of phonon and impurity scattering self-energies agree quantitatively with experiments.

A compact model of the Ferroelectric Tunnel Junctions (FTJs) device is constructed, using the Wentzel–Kramers–Brillouin (WKB) approximation for tunneling current calculation.
Bandgap Manipulation of Armchair Graphene nanoribbon
01 Sep 2020 | | Contributor(s):: Lance Fernandes
Bandgap Manipulation is very important for various applications. Optical Devices need smaller Bandgap where as Diode's need larger Bandgap. Armchair graphene Nanoribbon (AGNR) has a special property where if the numbers of atoms are multiple of three or multiple of three plus one, they are...

Mechanical Exfoliation as a Route to Nanomanufacturing of 2D van der Waals Bonded
11 May 2020 | | Contributor(s):: Daryl Chrzan
In this talk I present a mechanical exfoliation method able to reliably produce large patterned monolayer samples and place them with upon a substrate in desired locations. The method relies on the epitaxial strain imposed upon the layer to be exfoliated by the deposition of a thin metallic film.

Turning Fruit Juice into Graphene Quantum Dots
06 Jan 2020 | | Contributor(s):: John Gomm, NNCI Nano
Graphene, a sub-nanometer thick sheet made of carbon, was isolated just over a decade ago (2004), yet swiftly won the Nobel Prize for Geim and Novoselov in 2010 for its properties of high strength, conductivity, and transparency. Students will replicate the procedure used to isolate graphene...

Electronic Structure and Transport Properties of Graphene on Hexagonal Boron Nitride
06 Dec 2018 | | Contributor(s):: Shukai Yao, Luis Regalado Bermejo, Alejandro Strachan
Graphene is a zero-bandgap conductor with high carrier mobility. It is desired to search for an opening of band structure of graphene such that this kind of material can be applied in electronic devices. Depositing hexagonal Boron Nitride (h-BN) opens a bandgap in the band structure of...
