Hi, if in the case of doped nanomaterials the add ion enters the lattice ,then this mean in the case of composite structure the added ion does not enter the lattice? is that correct, please?
From my knowledge simply tells the amount of adding impurities (doping) is determine the system. Suppose you add less or equal to 5 wt% it is called doping and above this limit or whenever you got the second phase it is called compound or composite.
