Abstract
A method of substantially offsetting polarization charges in an electronic device having a heterobarrier comprising providing a substrate; providing at least one pair of stacks of semiconductor materials; one of the pair of stacks having one or more of spontaneous and piezoelectric polarity where the total polarization charge is opposite to the other of the pair of stacks; whereby due to the opposing polarities, the polarization is balanced and the pair of stacks operate to store electrical energy.
