ABSTRACT

The quantum mechanics postulates are shortly revived towards of their application in providing the basic crystal Bloch theorem and of further specialization to the quantum modeling of crystals in reciprocal space, on various levels of electronic behavior from free to quasi-free, to quasi-binding, to tight-binding models, as well as for modeling solids by quantum statistical means, especially grounded on Fermi statistics driving the valence-toconducting levels’ displacements so providing the quantum framework for semiconducting electrons and to chemical related moletronics.
