WebThis challenge probably is due to the localized nature of the O 2p derived valence band which leads to difficulty in introducing shallow acceptors and large hole effective masses. In 1997 Hosono and co-workers (1997 Nature 389 939) proposed the concept of 'chem. modulation of the valence band' to mitigate this problem using hybridization of O 2p … WebWithin the depletion approximation we suppose p n 0 in the depletion region. Another assumption is that all acceptors are ionized. The charge increment dQ s appears due to a slight increase in the space charge region width. The term dN A/dV was neglected, assuming NA does not depend on voltage.
