How to calcualte C-C bond energy of diamond by DFT

Click For Summary
SUMMARY

The discussion focuses on calculating the C-C bond energy of diamond and the dangling bond energy on the diamond surface using Density Functional Theory (DFT). Participants suggest utilizing resources like APS or PROLA papers for further information. The term "dangling bond energy" is clarified as "vacature formation energy," emphasizing the importance of precise terminology in computational materials science. The conversation highlights the necessity of specific software tools for conducting these simulations.

PREREQUISITES
  • Understanding of Density Functional Theory (DFT)
  • Familiarity with computational materials science
  • Knowledge of bond energy concepts
  • Experience with simulation software for DFT calculations
NEXT STEPS
  • Research the calculation methods for C-C bond energy using DFT
  • Explore the concept of vacature formation energy in diamond
  • Learn about available DFT software tools such as VASP or Quantum ESPRESSO
  • Review relevant literature on diamond bonding from APS or PROLA
USEFUL FOR

This discussion is beneficial for materials scientists, computational chemists, and researchers focused on diamond properties and DFT simulations.

Concerning the binding energy : well, there are different systems. Can you download APS or PROLA papers ? If so, you can send you some links.

Same goes for the "dangling bond energy" which i think is better reffered to as "vacature formation energy".

What software are you using to do these simulations ?
