Title : The Crystalline Accommodation Law Quantum Quantitative Model (CALQQM)

Abstract:

In solids the most important issue is to determine the energy of the electron rather than its position at any time. The electrons are always confined in their primitive cells and replace each other when moving. The crystalline accommodation law quantum quantitative model (CALQQM) can successfully get the exact relation between the crystalline structure of the solid and its energy band structure. Tarek’s law relates the energy space by real space and can precisely determine the energy levels of each element or compound. Moreover it can predict exactly the values of the work functions of the elements and compounds. The calculations were carried out on 16 elements of different valencies, which are: Li, Na, K, Au, Ag, Au with valency (+1), Mg, Zn, Cd with valency (+2), Al, In, Tl with valency (+3), Sn, Pb with valency (+4) and Bi, Sb with valency (+5).  In addition to group IV elements including the allotropes of carbon and the allotropes of tin such as; graphite (C-hex), diamond (C-dia), fullerene (C-60), and Alpha-Sn. The results showed that precise prediction of the work function of the elements, which is conclusive evidence on the validity of this model.

Biography:

Tarek Neyazi Ali El Ashram was born on 14 July 1967 in Aga, Dakahelia, Egypt. He is currently working as a Full Professor of Materials Physics at the Faculty of Science, Port Said University, Port Said, Egypt. He has published 30 papers that contributed to science, including the crystalline accommodation law (CAL-2015), quantum quantitative model (CALQQM-2024), and Egypt pyramids model for nanotechnology (EPMN-2025). Using these models, he has addressed important problems in solid-state physics such as the crystalline structure of materials, energy levels of electrons in solids, work function of materials, room temperature superconductivity, and nano-phenomena.
