Abstract
An electronic device comprising a substrate; a pair of stacks of polar semiconductor materials which create a charge by spontaneous and/or piezoelectric polarization; one of the pair of stacks having a spontaneous and/or piezoelectric polarity which is in a direction opposite to the other of the pair of stacks; whereby due to the opposing polarities, the polarization is balanced. A method of substantially eliminating the bias required to offset polarization charges in an electronic device having a heterobarrier comprising providing a substrate; growing at least one pair of stacks of semiconductor materials; one of the pair of stacks having a spontaneous and/or piezoelectric polarity which is opposite to the other of the pair of stacks; whereby due to the opposing polarities, the polarization is balanced to substantially eliminate the need for a voltage bias.
