To generate such a superstructure you need to work out (aided by experiment) the relevant epitaxial relationship between the two, then create the appropriate nxm 2D semicoherent interface and extend in the third direction to a periodic structure. This is a complex problem in bicrystallography. If

I suppose that you have TiO2 rutile, and ZnO rocksalt, so what do you mean by one layer? Also, they have very different unit cell parameters TiO2; 4.57, 4.57, 2.93, ZnO; 3.81, so how can you put them one on top of the other? Let me rewrite the question. We want

Thanks a lot Prof. Delamora for your reply. Let me rewrite the question. We want to make a heterostructure of TiO2/ZnO, just two layers for now. Your response is highly appreciated. Kind regards Lawal On Sunday, April 28, 2019, 7:01:09 AM GMT+8, delamora wrote: #yiv7308072348 P

Dear Developers and Users, I need your help to generate unit cell of a semiconductor structure of two layers of different materials. Any hint is highly appreciated. Your question is not clear... There are many possibilities Do you want to put two layers?
