Relativistic band structure and spin-orbit splitting of zinc-blende-type semiconductors

摘要: Zinc-blende-type semiconductors differ from their diamondlike counterparts by the absence of inversion symmetry. This produces a number spin splittings and spin-orbit coupling effects which are absent in latter. For instance, all states at general k split interaction. Also, bonding antibonding p-like coupled same Many these calculated here on basis ab initio self-consistent fully relativistic linear-muffin-tin-orbital method. better understanding interpretation results, semiempirical parametrized 16\ifmmode\times\else\texttimes\fi{}16 k\ensuremath{\cdot}p calculations several types performed. Particular emphasis is placed determining signs an unambiguous manner. The results compared with available experimental data rather diverse origin.
