The molecule having $D_{3d}$ symmetry is considered herein as an example. The symmetries of normal vibrations active in Jahn-Teller's effect were defined. $E-E$ vibronic interaction was considered to obtain vibronic potential energy in a matrix form and thus the adiabatic potential. Significant differences are shown in the construction of a secular matrix $D(\\vec{k})$ for defining a dispersion law for charge carriers in the crystals and the matrix of vibronic potential energy, which depends on the normal coordinates of normal vibrations active in Jahn-Teller's effect. Dispersion law of charge carriers in the vicinity of $\\Gamma$ point of Brillouin zone of the crystal with $D_{3d}^2$ symmetry was considered as an example.", "revisions": [ { "version": "v1", "updated": "2014-07-09T10:40:31.000Z" } ], "analyses": { "keywords": [ "charge carriers", "dispersion law", "adiabatic potential", "semiconductor crystals", "vibronic potential energy" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1407.2427B" } } }
