define conductivity, paramagnetism and diamagnetism
recognise conductors and insulators by their conductivity
understand the definition of a polymer and be able to distinguish linear, branched and cross linked polymers
describe the distinguishing features of nematic and smectic liquid crystals
use, define and explain the concepts of conduction band, valence band, band gap, hole, acceptor level, donor level, n-doping and p-doping
explain the relationship between band gap and electrical and optical properties • explain how n or p doping gives rise to conductivity of electrons and hole
