Dear colleagues and VASPKIT users, We are pleased to announce that the official and comprehensive VASPKIT user guide, “Empowering Materials Science with VASPKIT: A Toolkit for Enhanced Simulation and Analysis,” has been published in Nature Protocols. This marks a significant milestone for the VASPKIT project and underscores its growing impact within the international materials science community. From its initial development to now exceeding 6000 citations, VASPKIT has benefited greatly from the support...
I thought you said you're using vaspkit? And it automatically s shifts the FERMi level to zero.

The FERMi energy is already shifted by default.

I truly appreciate your prompt response. I upgrade VASPKIT version 1.4.1 to 1.5.1 and it now works!
Kindly upgrade VASPKIT to version 1.5.1 and try again. 2024年11月13日 12:08,Jungho Kim junghokim@users.sourceforge.net 写道: Hello, I'm attempting to get the magnetic anisotropy energy (MAE) of a ternary alloy using VASPKIT.

The interactive methods works, but I want to use the command line so that I can incorporate the commands into a bash script to automate the process. Is there no way to use the vaspkit command line method to calculate charge density difference?
Use the interactive method instead. Type vaspkit and select the appropriate task you want to perform and specify the corresponding charge densities On Wed, Jul 10, 2024 at 4:19 PM Ruby Keesey rkeesey@users.sourceforge.net wrote: I am trying to run charge density difference calculations using VASPkit from my command line.

Dear All, May I ask how one can add Brillouin zone along 3D band structure image? As it is shown in the gallery image attached (a, c) Thanks in advance, and thanks a lot for making vaspkit available to all users.
Got it. Thank you so much sir for all the suggestions and discussion.
It is common sense that semiconductor has no Fermi surface. You should use a metal such as copper to test this utility. 2022年7月12日 19:16,Himanshu Sharma hammerman@users.sourceforge.net 写道: Soory Sir, I am not able to understand your point.

You cannot plot the Fermi surface for semiconductors. You can only plot the energy surface below VBM or above VBM. 2022年7月12日 13:30,Himanshu Sharma hammerman@users.sourceforge.net 写道: But sir, Is it ok to do so? Because the fermi energy that is currently written on FERMI_ENERGY.in is matching with OUTCAR file. And if it is ok to change, what value should I choose? Can I set the fermi energy equal to VBM?

You need to shift the Fermi energy manually in the second line of FERMI_ENERGY.in http://fermi_energy.in/ file to ensure several band cross this value. 2022年7月12日 01:59,Himanshu Sharma hammerman@users.sourceforge.net 写道: Thanks for the suggestion but problem remainsas it is.

Hello, Himanshu Sharma. Silicon has no Fermi surface.
