Part 3/8:
The video explains how energy levels in atoms transform when spaced closely together in a lattice. As atoms form a solid structure, conduction and valence bands may overlap, complicating energy processes. Grenier describes methods to "pull apart" these bands, such as manipulating atomic clusters of nickel to modify these bands effectively.
Critical Methods of Separation
Grenier outlines various techniques to achieve the necessary atom separation to create distinct conduction and valence bands. For instance:
- Cluster Size Control: Pintilie argues the number of nickel atoms in a cluster is critical. A defined range promotes successful electron separation.
