I am trying to find the frequency of transition state in NEB calculation. How to calculate, and what parameters are required in INPUT file for VASP? For 2D materials
Please have a look at these detailed step-by-step instructions: How to set up an NEB calculation
Also, mind that you probably need electrostatic corrections and selective dynamics for a 2D system.
For future posts, please first have a look at the VASP Wiki as stated in the forum guidelines. If you can't find the answer there, we are happy to help.
Does this help to get you started?
