conductivity - Is there a material that turns from being electrically . . . For my project I am looking for a material which can turn from being electrically conductive to nonconductive (has to be irreversible) upon exposure to electromagnetic radiation (say UV) I tried googling for my question but found no relevant answer A short explanation or a link would be greatly appreciated
Why is the conductivity of non-metals not equal to zero? When we think of molecules we think of their molecular orbitals If we place these molecules into an ordered solid like a crystal, then the orbitals on adjacent molecules are close enough to interact and "extended" molecular orbitals are formed

Are all covalent compounds non-conductors of electricity? Covalent compounds with macromolecular structures are often semiconducting Setting aside single elements, an obvious example is provided by gallium arsenide,, whose semiconducting properties are used in electtonic devices
How does graphite content affect the conductivity of pencil lead? My peers and I started an experiment to test whether we could use the conductivity of a piece of pencil lead to determine its grade (that is, whether it is 2H, HB, 3B etc ) The paper Observational
conductivity - Why are ionic compounds bad conductors of electricity in . . . Ionic compounds do not conduct electricity in solid state because electron motion results in electricity being conducted but in solid state the constitutive particles are strongly bonded or in fixed positions; thus, they can't move from one part to another
