The amplitude and periodicity of the re#ection high-energy electron di!raction (RHEED) oscillations displayed strong temperature dependence in homoepitaxy of SrTiO 3 (STO) "lms. Combining with the AFM observations, the results suggest that the oscillations are not directly related to the layer-by-layer growth. ( 2000 Elsevier Science B.V. All rights reserved.

Effective nuclear charge, the charge an electron experiences after accounting for the shielding due to other electrons, increases from left to right across a given period, thus an electron in a 2p orbital of a nitrogen atom experiences a greater Zeff (3.83) than an electron in a 2p orbital of a carbon atom (3.14). This trend makes sense if we consider what happens to atomic structure as we move...

participation is a process in which people involved to make endeavors aiming at a common goal; and they do this actively, freely with awareness and accountability. women participation as one of the principles for development can be studied from different perspectives. the objective of the present study is to investigate social and cultural factors influencing social participation of rural women...

Using NC-AFM with CO terminated tips, atomic resolution on molecules has been demonstrated and the contrast mechanism was assigned to the Pauli repulsion [2] (see Fig.1c) . On the other hand, by using STM and by decoupling the molecules from the metallic substrate by an ultrathin insulating film, the molecular frontier orbitals, i.e. the highest occupied and the lowest unoccupied molecular orbi...

orbital fat adherence syndrome is a known complication of strabismus, orbital and scleral buckling surgery or orbital trauma which induces a restrictive strabismus. in this case presentation we introduce a surgical method of globe slinging using temporalis fascia for correction of restrictive esotropia due to fat adherence syndrome. in our review of literature we found no report of a similar pr...

The transmission time of an electromagnetic signal in the vicinity of the earth is calculated to c and contains an orbital Sagnac term. On earth, the synchronisation of TCB can be realised by atomic clocks, but not the one of TCG. The principle of equivalence is discussed.

We evaluate all the electron-phonon couplings derived from the one-body electronic interactions, in both the adiabatic and extreme non-adiabatic limit, for a dimer with a non-degenerate orbital built from atomic wave functions of Gaussian shape. We find largely different values of the coupling parameters in the two cases, as well as different expressions of the corresponding terms in the Hamilt...

The calculation of magnetization densities in solids is reviewed. The atomic model is still a useful first approximation while the more involved band structure approach is required for first principle calculations of solid state spin densities. The calculation of orbital contributions, either induced by an applied field or caused by spin-orbit coupling, is discussed.

We performed all-electron ab initio self-consistent field Hartree-Fock linear combination of atomic orbital, in which electronic correlation using density functional were included to perform electronic calculations in MgB2 new superconductor. Superconductivity in this compound was correlated with existence of px,y band holes at Γ point. Typeset using REVTEX
