Solid state physics 111/20/2023 ![]() ![]() ![]() Solids(at a given temperature, pressure, volume)have stronger interatomic bondsthan liquids.Solidscan be crystalline, polycrystalline, or amorphous.Solidsconsist of atoms or moleculesundergoing thermal motionabout their equilibrium positions, which are at fixed pointsin space.Applying anelectric field rotates the dipole & establishes order within thecollection of molecules. Liquid Crystalshave mobilemolecules, but a type of long rangeorder can exist the molecules havea permanent dipole.Applying low levels of thermal energy can easily break the existing weak bonds. Similarto gases, Liquids have no atomic/molecular order & they assume the shape of their containers. These molecules haven’t any particular order & move freely within a container.Gaseshave atoms or molecules that do not bond to one another in a range of pressure, temperature & volume.The (Common) Phases of Matter This doesn’t include Plasmas, but these are the “common” phases!! “Condensed Matter”includes both of these.We’ll focus onSolids! Solid State Physics is about many different kinds of solids.We'll discuss the microscopic physics of mostly,CRYSTALLINEsolids, including metals, insulators, & semiconductors. ![]() To expose students to the rich, broad, varied field of SOLID STATE PHYSICS.Elementary Solid State Physics: Principles & Applications, M.
