A neutron-scattering study of nonsuperconducting La2-xSrxCaCu2O6 (x=0 and 0.2), a bilayer copper oxide without CuO chains, has revealed an unexpected tetragonal-to-orthorhombic transition with a doping dependent transition temperature. The predominant stru ...
Using a density functional approach, we determine the relative stability of various oxygen species in alpha -quartz. We considered interstitial species in the form of atomic and molecular oxygen, as well as network species, such as peroxyl and ozonyl link- ...
Collagen is constituted of three polypeptides forming a triple helix maintained by numerous weak chemical interactions, such as hydrogen bonds. In connective tissue it further packs into very long cylinders of few nanometers of diameter, called fibrils. On ...
Using a first-principles approach, we assess the validity of a picture for the energetics at Si-SiO2 interfaces based on bond energies complemented with penalty energies for silicon atoms in intermediate oxidation states. By total-energy calculations on cl ...
We report on a 2×2 SOI switch, based on the plasma dispersion effect, reaching 5 MHz of switching frequency. Measured insertion losses, extinction ratio and crosstalk at 1300 nm and 1550 nm are presented and discussed. ...
A monolithic silicon integrated optical micro-scanner is presented. The device consists of a mirror located on the tip of a thermal bimorph actuator beam. The fabrication process is very simple and compatible with IC fabrication techniques. The device is e ...
When silicon thin films are deposited by plasma enhanced chemical vapour deposition in a plasma regime close to that of the formation of powder, a new type of material, called polymorphous silicon (pm-Si), is obtained. We present here the optoelectronic an ...
First-principles total energy calculations are carried out to investigate the relative energetics of several neutral oxygen species in alpha-quartz and amorphous SiO2. We considered both atomic and molecular oxygen, as interstitial and network species. The ...
For the low-spin t2g6 Ru(OH2)62+ (ΔV⧧ = −0.4 cm3 mol-1) and Rh(OH2)63+ (ΔV⧧ = −4.2 cm3 mol-1) hexaaquaions, the respective Id and Ia water exchange mechanisms had been assigned, mainly on the basis of activation volumes ΔV⧧ and entering ligands effects for ...
Using a first-principles approach, we characterize P-b-type defects at Si-SiO2 interfaces by calculating hyperfine parameters for several relaxed structural models. Application to the Pb center at the Si(111)-SiO2 interface, for which the atomic structure ...
