A Lefèvre,LJ Lewis,L Martinu,MR Wertheimer 摘要: Classical molecular-dynamics simulations have been carried out to investigatedensification mechanisms in silicon dioxide thin films deposited on anamorphous silica surface, according to a simplified ion-beam assisteddeposition (IBAD) scenario. We compare...
Using classical molecular-dynamics simulations, we worked out a simple model of Ion Beam Assisted Deposition (IBAD) of silicon dioxide on an amorphous silica substrate, in view to in- vestigate the modifications of the structural and vibrational properties induced by medium-energy bombardment. Atoms...

Upon interactions, the bond length of the Lewis base (carbonyl) is increased, which polarizes the electron density towards the Lewis acidic site (Si surface atom). The lengthened bond is clearly seen in Fig. 1a as a shift to a lower-energy vibration in the ATR-FTIR spectrum. The ...

Although the normal coordination number of silicon is four, the atom still acts as a Lewis acid, especially if the silicon is bound to electronegative ligands and hence coordination numbers of five and six are possible. However, because of equilibria it is not always possible to establish the ...
Imagine if it were possible to create 3D objects in the palm of your hand within seconds using only a single photonic chip. Although 3D printing has revolutionized the way we create in nearly every aspect of modern society, current 3D printers rely on la
