How can i calculate the band alignmet of Sc2CO2/BlueP heterostructure from DFT?

I know the work function and band gap of each monolayer and heterostructure. I calculated mulliken electronegativity(X) of Sc2CO2 and Bluep. From that i found Ev = X- 4.5+Eg Ec = Ev-Eg, where Eg...

In general, yes. Consult any good book on solid state physics, such as that by Ashcroft and Mermin (search on the term Bragg planes); in the latter book, you may also wish to consult Chapter 9 (see in particular Fig. 9.3 on page 158 -- here note that |UK| need not take the same value on all Bragg planes, except for reason of symmetry).

Thanks! I will find it !)

You are welcome.
