What is the piezoelectric effect? Describe the piezoelectric effect in barium titanate.
The piezoelectric effect refers to the generation of electric charge in certain materials when they are subjected to mechanical stress. This effect occurs in materials that lack a center of symmetry in their crystal lattice, which allows them to produce ______ ________ _____ __________ _____ _______ _______ ____ _____ _________ ___.

For a free electron gas in two dimensions, derive the relation between the number density of electrons and the Fermi wave vector.
Calculate the total voltage difference (the built-in potential) between the n-type and p-type part for a uniformly doped Silicon p-n junction with Nd = Na = 1023 m-3 at room temperature. The intrinsic carrier density is 1.45 x 1014 m-3. Will the built-in voltage increase or decrease with an increase in temperature?
