Thank you so much for this informative video. Actually, I am beginner and would like to ask two question; 
1. Can we add any impurity atom or only particular atoms having some properties similar? 
2. Could you make a video regarding to certain percentage like 10%, 12% 25% or any other % of impurity in any parent compound?

Hounerable Admin, Thanks a Million

@deerghshahi5944

Is it necessary to add vacuum before doping in bulk though vacuum is necessary between layers before doping?

@abhanan3337

Thank you, how can we transforme this strucutre into a monolayer 2D strucutre?

@zahidurrahaman428

Thank you for this helpful tutorial.

@deerghshahi5944

Could you please explain what types of atom is used to dop in crystal ? should impurity atom have same valency of electronegativity or other else?

@sihemlakehal1918

Thanks a lot, I have one question: what is the importance of the addition of vacuum in the relaxation and electronic calculation?

@tldian

What is text editor do you use? How to download it?

@attaurrahman6529

Hi sir. Can u plz tell me the percentage amount of oxygen atom u doped in the structer

@juanrafaelgomezquispe6701

thank you, you really help me :´)

@arijeetsarangi6613

what to do if the stochiometry is changing while converting to xyz file ?

@shaheengulshanah448

Can you please do the same for (110) plane for TiO2 or SnO2? It will be of great help.

@kkm5384

Sorry for my curiosity, i still dont understand clearly TWO things from your videos.
1. Why do you delete one layer from a and b directions while making vacuumn or any such, for the sake of periodic boundary?
2. Why you save as .XYZ file and then copy them into VASP type file?
