No. You call the regular configuration of atoms of a particular material like GaAs a lattice.
Now when you start to grow one type of material on top of another in a regular fashion like layers in a sandwich:
10 nm GaAs
5 nm InAs
10 nm GaAs
5 nm InAs
You get what is called a super lattice. It is not an atomistic lattice, but a lattice of material type A and B.
- 8note 9y agoso the difference is that super latices are thicker?
- deepnotderp 9y agoGot it, so they've figured out how to deal with lattice constant mismatches?
- splittingTimes 9y agoYes they did. That's why you will mostly see combinations of binary materials like GaAs, InAs, AlAs to form super lattices.
