I have a theory that contrary to popular belief hot air does not rise, (at least of its own accord) but that it only appears to do so because it is forced out of the way by colder, denser air. Does anyone agree?

I'm studying transparent conducting oxide now. One of the requirement of TCO materials is >> there can be no interband transition less than 3.1 eV in energy. This limits consideration to cations with filled d-shells, such as 3d10Cu+, Zn2+, Ga3+, 4d10 Ag+, Cd2+, In3+ and Sn4+.

Could somebody explain to me what does it mean ? Thanx
