The Structure of Solids, Liquids,

and Polymers

PRINCIPAL FACTS AND IDEAS

1. Crystalline solids possess a geometrically repeating lattice structure.


2. The Einstein and Debye crystal models describe vibrations in crystals.


3. The band theory describes the electronic structure of solids to a useful
   approximation.


4. Liquids can be modeled as though they were very dense gases or as
   though they were disordered solids.


5. Transport processes in liquids can be modeled as motions of molecules
   as though temporarily confined in cages made up of neighboring
   molecules.


6. Polymers are made up of monomer molecules covalently bonded into
   chains or networks.


7. Nanomaterials consist of particles roughly one nanometer in size.
