Question

How would cs doping affect the lattice parameters?

Answer 1

Explanation:

Hi , it depends on the size of doping element and your material. like , if you dope Nb in SrTio3 thin film, It shows that lattice parameter is increased in case of Nb doping in SrTiO3 . because , Size of ionic radius of Nb(5+) is 78 pm which is bigger than the ionic radius of Ti(4+) . so , If Nb is doped in SrTiO3 , Nb will substitute Ti , as a result , lattice parameter will increase .

you may see the following article --------- ( see the table 1 of the following article)

charge separation under standard solar irradiation†

and Edson R. Leite*

So , If the size of doping element is smaller than its substituting element , then lattice parameter will decrease and vice versa.
