Electron dot structures, also called Lewis structures, are a graphical representation of the way electrons are distributed throughout a compound. Each element's chemical symbol is surrounded by lines, representing bonds, and dots, representing non-bonded electrons. When drawing an electron structure, ...
structure? electron dot structures or lewis dot formula can be drawn if the molecular formula of the compound is known. it defines the nature of bond and position of atoms of the molecule which are connected in the molecule. the representation of molecules in lewis electron dot structure or ju...
The electronic structure of a spherical quantum dot with a finite confining potential has been investigated. The wavefunctions and the total energy of the quantum dot have been calculated using the Quantum Genetic Algorithm and Hartree–Fock Roothaan method. The relativistic energy corrections have ...
In this system, the energy structure of the absorber material and of the electron extracting material can be easily tuned via a variation of quantum-dot size, allowing us to tailor the energetics of the transfer process for device applications. The efficiency of the transfer process increases ...
The trends found in the physical and chemical properties of the group 16 elements (O, S, Se, Te) and their compounds justify the notion that these elements constitute a family. Theoretically calculated values of a number of components of the experimentally derived electronic energy of the group...

Vacuum field structure of a helical laser beam As shown in Fig.1a, we consider a laser beam propagating in the positive direction along thex-axis. In the case of a beam with helical wave fronts, it is convenient to represent the spatial structure of each field component as a superposition...
