Electron spectroscopy measurements (UPS, XPS, and AES) of the heavy polyvalent liquid metals Hg, Tl, Pb and Bi reveal the systematic evolution of well separated 6s/6p bands with increasing widths of the bandgaps and increasing p bandwidths with increasing number of p electrons. The presence of...
The valence electron structure of Fe_2B phase was studied on the basis of Yu's empirical electron theory of solids and molecules.The values of valence electrons on every bond in an atomic coordinate cluster were calculated by the method of bond length difference(BLD). The results showed that ...
In the first few superactinides, the binding energies of the added electrons are predicted to be small enough that they can lose all theirvalence electrons; for example, unbihexium (element 126) could easily form a +8 oxidation state, and even higher oxidation states for the next few eleme...

CAl3X (X = B/Al/Ga/In/Tl) with 16 valence electrons: can planar tetracoordinate carbon be stable? As a perpetual chemical curiosity, planar tetracoordinate carbon (ptC) that violates the traditional tetrahedral carbon (thC) has made enormous achievement... Hai-Feng,Zheng,Shuang,... - 《Ph...
Spectral functions of the Falicov-Kimball model with electronic ferroelectricity We calculate the angular resolved photoemission spectrum of the Falicov-Kimball model with electronic ferroelectricity where $d$- and $f$-electrons have di... WG Yin,WN Mei,CG Duan,... - 《Physical Review B》 被引...
Acronyms Encyclopedia Wikipedia Related to valence band:Fermi level valence band n. The outermost electron shell of atoms in an insulator or semiconductor in which the electrons are too tightly bound to the atom to carry electric current.
By combining a recent result of March and Matthai for the energy gap G with a model of Rey and Savin, the correlation energy e c of the valence electrons embracing C, Si, Ge and Sn can be estimated. While Sn is thereby predicted to have e c near to the Ceperley-Alder jellium resul...
(~0.35–0.4 eV) means that they need to be cooled to reduce their large dark currents. Monte Carlo simulations show that in most III−V semiconductors capable of room temperature operation (i.e.,Eg ≥ 0.7 eV), both electrons and holes undergo significant scattering prior to ...
12.Quantum mechanics uses complex number wave functions (sometimes referred to as orbitals in the case of atomic electrons), and more generally, elements of a complex vector space to explain such effects.量子力学用复数波功能(有时指轨道内的原子电子),而更通常用复向量空间原理来解释这类作用。
