How can I obtain the reciprocal lattice of graphene?

SUMMARY

The reciprocal lattice of graphene is identified as a honeycomb structure, which can be inferred from the systematic absences of peaks observed in Low Energy Electron Diffraction (LEED) patterns. Graphene, while not a Bravais lattice, is derived from a hexagonal lattice with a basis of two atoms. Understanding the reciprocal lattice involves recognizing the unique characteristics of non-Bravais lattices and their corresponding lattice vectors.

PREREQUISITES
  • Understanding of reciprocal lattice concepts
  • Familiarity with Low Energy Electron Diffraction (LEED) techniques
  • Knowledge of hexagonal lattices and Bravais lattices
  • Basic principles of crystallography
NEXT STEPS
  • Research the calculation methods for reciprocal lattices of non-Bravais lattices
  • Study the systematic absences in diffraction patterns for different crystal structures
  • Explore the relationship between real and reciprocal lattices in crystallography
  • Learn about the implications of lattice structures on material properties
USEFUL FOR

Researchers in materials science, physicists studying crystallography, and anyone interested in the structural analysis of graphene and similar materials.

I have a question about reciprocal lattice of graphene.
When we see LEED pattern, we can know that reciprocal lattice of graphene is honeycomb.
But how can we know theorically that it is honeycomb?
Hexagonal lattice or other bravais lattice has just lattice vectors which don`t contain baises.
So it is just straight forward.
In case of graphene which is not a bravais lattice, how can we get a reciprocal lattice?

The lattice is hexagonal, dot. The structure is honeycomb. You can infer this from sytematic absences of peaks.

Thank you for your answer.
But I just know that how can we calculate reciprocal lattice in case of not a bravais lattice.
 
All lattices are bravais lattices. Aa honecomb structure (not lattice) is formed from a hexagonal lattice an a basis consisting of two atoms.
