Insulators: With increase in temperature, the conducting property increases. So we call the semi-conductor material have negative temperature coefficient i.e. with increase in temperature, resistance decreases. Semiconductors: With increase in temperature, the conductivity of the semi-conductor material increases. As with increase in temperature, outermost electrons acquire energy and hence by acquiring energy, the outermost electrons leave the […]

Types of material & their comparison
In electronic devices we mainly use 3 types of materials for manufacturing purposes. Conductor Insulator Semiconductor Conducting materials are those materials in which electrons of the outermost shell are weakly bonded with nucleus. Hence as force of attraction between nucleus and the outermost shell electrons is weak, the outermost electrons become free and roam in the […]
