Hey!
The answer to your query is Semiconductors. Semiconductors act as perfect insulators at low temperatures and conductors at higher temperatures. At higher temperature, conduction takes place because the electrons surrounding the semiconductor atoms break away from their covalent bond and move freely in the lattice.
