Conduction in conductors and semiconductors Mobility μ: In good conductors like metals, free electrons exist in abundance. They are supposed to be accelerated under…

Energy-band Concepts of Materials The electron energy levels for a single free atom in a gaseous medium are discrete, since the atoms…

Currents in metals are due to the movement of charge carriers ‘electrons’. where I is the current in Amperes and A is the cross-sectional area of…

The value of conductivity of a material gives us an estimate of the extent to which a material supports the flow of…
