Questions Project 4. Curved Graphene

Java Python Questions Project 4. Curved Graphene

1.- a) What types of curvature can be present in a graphitic structure? Explain and show pictures with examples. (cite all sources. See New Journal of Physics, Terrones H and Terrones M., 2003).

b) How does curvature is related to the genus of a closed compact surface?

2.- a) In case of triply periodic graphene or Schwarzites how can the genus be found? Explain (cite all sources) and use the following structure to calculate the genus:

b) Wha Questions Project 4. Curved Graphene t is a triply periodic minimal surface and what is its relation to Schwarzites?

c) What electronic properties can be found in Schwarzites (cite all sources).

3.- Find the genus of the structures “a”, “b” and “c” put in the LMS as part of this project and draw an image of them using Vesta.

4.- Is it possible to get a closed compact graphenic structure (not periodic) with just heptagonal and hexagonal rings of carbon? Justify clearly your answer.

5.- Print using a 3-D printer structures “a” and “b”
