My Presentation at the Marie-Curie Conference in Florence, 25-26 Novembre 2013. It was a short presentation given to a general audience of researchers and Marie-Curie fellows in all disciplines (from Scholars in Humanities to Medical Doctors). From blog post on http://www.iannaccone.org/?p=2287

1. Graphene and
2D electronics

13. Graphene
(Manchester UK 2004)

14. Graphene is just one atomic layer
of graphite
Can it be a “new” material ?

15. In 2004 A. Geim and K. Novoselov isolated
and characterised graphene at Manchester
Univ.
2010 Nobel Prize for "for
groundbreaking experiments regarding
the two-dimensional material
graphene”

16. A material with
exceptional properties
• Stable in single monolayer form
• A truly 2D material (as thin as physically possible)

17. A material with
exceptional properties
• Stable in single monolayer form
• A truly 2D material (as thin as physically possible)
• Excellent electrical conductor (up to 1000x Si)
• Excellent thermal conductor

18. A material with
exceptional properties
• Stable in single monolayer form
• A truly 2D material (as thin as physically possible)
• Excellent electrical conductor (up to 1000x Si)
• Excellent thermal conductor
• Transparent and flexible
• Exceptionally Strong (300x Steel)

19. Graphene in Electronics?
Problem:
Graphene has
a zero energy
gap
Transistors
cannot be
switched off

20. Rules of the game
20
Increase gap and fabricate transistors, but
keep high mobility and reproducibility

21. Other 2D Materials
Boron Nidride
Et cetera …
Molybdenum disulfide

22. Our specialty: Early assessment of
device potential
NanoTCAD VIDES
3D atomistic device simulator
Released as open source as a
python module at

Fiori (UniPi) lead developer]

23. “This won’t work.
This neither.
Try instead this”
