[No Mic] Bi2Se3 Monolayer and Bilayer in VESTA
Просмотров 4,4 тыс.2 года назад
In this video, we use VESTA to make a monolayer and bilayer of Bi2Se3, a popular topological insulator. Comparing our structures with Figure 1 in the paper, PHYSICAL REVIEW B 88, 045312 (2013), it appears that we make the (111) surface in this video. Please note I may be mistaken, as I just checked by visual comparison. Link to materials cloud 2d crystal structure database for Bi2Se3: www.mater...

In this video, we use LatticeMixer and VESTA to build and analyze an interface between cubic CsPbBr3 (001) and cubic Au (001). Please note that the perovskite crystal surface here may is not stoichiometrically balanced nor charge neutral (assuming native oxidation numbers). One likely needs to add atoms/molecules to passivate dangling bonds on the surface of the perovskite crystal and bring cha...

In this video, we make the (110) surface slab of MAPbI3 and then interface it with graphene to make a heterojunction that I found in this paper (below): pubs.acs.org/doi/10.1021/acs.jpcc.8b03230 There are 3 main concepts covered in this video: 1. slab cutting of MAPbI3. This is nontrivial becuase we have to be careful about some iodine atoms in the vacuum axis dimension 2. Orthogonalize the hex...

Sir, why you are not posting for the last two years?
please make a mono layer of 1T-TaS2
Can you suggest how to change the hexagonal MoS2 structure to cubic structure by using rotational matrix in vesta software?
Can we make moiré superlattices in VESTA as a vasp file? Thank you.
How we can obtain the monolayer from it?
very informative video. I am trying to find a transformation matrix to convert hexagonal crystal structure to tetragonal crystal structure. Can anyone help with the transformation matrix.
I have a small doubt, on changing the slab to (201) plane, using matrix values, the crystal becomes somewhat like compressed and kind of sandwiched, is that okay for the slab? FYI, the structure I have chosen is WP2, monoclinic structure from Materials project (ID: mp-11329).
Hi sir, I want to make a sheet of titanium oxide like graphene sheets, i ahev structue of it but i dont know how t o turn it in a sheet. Can you pleasehelp me with it?
10 by 10 sheet i meant
Hi, Nickel and Copper. Thanks for your video. How does this method control the layer number?
If I have a bulk bcc (110), how can I get a 110 surface
how do you get the lattice mismatch here? Or there are no mismatch? Also changing the lattice parameters will be accounted when we calculate for example vc-relax? I think this method is faster and better than using the code cell match.
Thanks for the tutorial, really appreciate the video quality. By the way, correct me if I'm wrong but the a* b* c* buttons seem to refer the basis vectors for the reciprocal lattice, and in this case since a b c is orthornormal it is its own reciprocal basis
thank you sir can you show result of this phase band and DOS
How to make pt 110 surface and how these transformation takes place
21:16 Just causally decided to look up the term "money shot" today... and accidentally learned the real meaning. Thought it was just like a important/crucial/memorable shot in a movie or something lol
What about lattice mismatch?
Did you teach cours of vesta
Hi ! hope you are well, thanks for the video, I want to ask if this kind of heterostructures can be used for Crystal23, if so, how can I put it into the input, because I am trying to run the optimization of geometry and the structure is failing, thanks again.
How can I know the transformation matrix for the 311 plane for cubic ZnFe2O4 structure, please?
one of the best HF method video on yt. thanks for content
hi how do add another unit cell to this one? I wanna have two connected ones
Really amazing tuto! How does the matrix looks like if I wanted the 111 phase of an FCC Co structure? Using the transformation matrix of this tuto, Co atoms get very close and problems arise during the ground state calc. I tried to apply the concepts discussed here and I got something really messy :(

Many thanks for this interesting video!
This is awesome 👍🏾👍🏾👍🏾👍🏾
Hi...this is great stuff. I am starting out with my phd work and this has been very handy. Your work has given me quiet some information to guide me in my research work on surface passivization pf perovskites. As i have gone through some of your work I have a few questions, I noticed a pattern one can use to prepare structures ready for first principles analysis, though I haven't really grasped it well. A suggestion video would be a walk-through on preparing structures for analysis for first principle analysis. Thank you and love your videos
Hey, good presentation, may you suggest me how to make tilt Coincidence site lattice grain boundary for monoclinic structure using VESTA?

Sir great efforts, Sir how I can make Fe Mono-layer? kindly guide me from very start, as I'm beginner
Hey, thank you so much! I have one additional question - why is it advantageous to move the slab to the center of the cell?

@nickelandcopper5636 Thanks for your video. also please make tutorial on "how to change space group". I do not know how to find a rotation matrix
make some vedios how we can make functionalized QD
Thank you so much! i need your help want to make a heterostructure of two different crystal like orthorhombic and cubic for siesta how i can do ?
Very helpful. Could you prepare a video demonstrating modelling of core-shell nanoparticle?
I am trying to build a Cu-MoTe2 system, with Cu as the elctrodes. Can you show how to proceed with this?
Thank you so much for your video! Do you know why choosing a rectangular base for the supercell instead of the one you showed here adds additional strain to the cell?
@nickelandcopper5636 It's a great and informative video. What about the next steps. Like introducing another species of atoms in this structure. please share that information.
Thank you for making these videos! I had a question about the angular momentum terms: for Carbon, for example. If using the STO-3G basis set, the p orbitals have the normalization constant A * x^la * y^lb * z^lc where the last part is the spherical part, and la+lb+lc = L (angular momentum quantum number). for the 2p orbital, la+lb+lc = 1 (-1, 0, and 1). So, would it be correct to assume the terms are the respective spherical harmonics? Also, would they be multiplied instead of added?
A correction to the question: the xyz part is included in the overlap matrix, so the normalization constant (in cartesian coordinates) is ((8alpha)^(la+lb+lc)*la!lb!lc! / (2la)!(2lb)!(2lc)!)^1/2 (found on wikipedia page for gaussian orbitals). for la=-1, would it be correct to use the absolute value when computing this part? Or I may be completely wrong about all of it, please let me know if you have time. Thank you!
Hello, Can you help me about this. I have generate the file for VASP. In the notepad there is about 21 atoms but when I opened it there are about 1000 atoms. Could you see the problem for me. Thank you
Sir can you please make a video on 3D hematite (Fe2O3) to 2D hematene
I am trying to make unit cell for Cu(110) surface. The final structure I am getting is BCC. Can you please verify if its correct? It will be really helpful..
Can you please explain how did you get the rotation matrix?
I don't know if this will completely help you, but the thumbnail of this video clinched it for me: ruclips.net/video/4Y1_y9DI_Hw/видео.html I was trying to do what he's (EDIT: by "he" I mean the person in the current video) doing, but with the (104) plane. The normal vector to this plane lies on the xz-plane, so luckily, I only had to think about rotating about the y-axis to <001>. Any rotation in three dimensions can be seen as a sum of three rotations about each of the three axes. If you can figure out those angles, then it's simple. My rotation worked, by the way. When I click "a" to make the a vector point out of the screen, the (104) plane is now perpendicular to the c-axis. I'm having an entirely different problem where the software is adding tons of extra atoms. I don't know why.
