Derivation of the effective-mass equation for a superlattice: A perturbational approach
We derive the effective-mass equation for a superlattice structure by considering the barrier as a perturbation of the bulk material in the well. The renormalization constants as well as the momentum matrix elements are allowed to vary with space in the resulting equation. Terms additional to the us...

Derivation of the effective-mass equation for a superlattice: A perturbational approach |
| abstract |
We derive the effective-mass equation for a superlattice structure by considering the barrier as a perturbation of the bulk material in the well. The renormalization constants as well as the momentum matrix elements are allowed to vary with space in the resulting equation. Terms additional to the usual effective-mass equation are found by using second-order perturbation. They are shown to have little effect on the subband separation and are small on the scale of the energy gap. |

The renormalization constants as well as the momentum matrix elements are allowed to vary with space in the resulting equation. Terms additional to the usual effective-mass equation are found by using second-order perturbation. They are shown to have little effect on the subband separation and are small on the scale of the energy gap.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">APS Digital Backfile Archive 1893-2003</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">von Allmen, Paul</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Physical review / B</subfield><subfield code="d">College Park, Md. : APS, 1970</subfield><subfield code="g">46(1992), 23, Seite 15377-15381</subfield><subfield code="h">Online-Ressource</subfield><subfield code="w">(DE-627)NLEJ248237845</subfield><subfield code="w">(DE-600)1473011-X</subfield><subfield code="x">1550-235X</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:46</subfield><subfield code="g">year:1992</subfield><subfield code="g">number:23</subfield><subfield code="g">pages:15377-15381</subfield><subfield code="g">extent:5</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://www.tib.eu/de/suchen/id/aps%3Aaf3853f6a3d2ba560bc00e3bebad9fa89425a773</subfield><subfield code="x">Verlag</subfield><subfield code="z">Deutschlandweit zugänglich</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-APS</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">46</subfield><subfield code="j">1992</subfield><subfield code="e">23</subfield><subfield code="h">15377-15381</subfield><subfield code="g">5</subfield></datafield></record></collection>
