An in-situ investigation of the interface evolution during MBE deposition of SrTiO3 on Si has been undertaken using x-ray photoelectron spectroscopy. This study revealed that the critical parameter to control the oxide/semiconductor interface is the incident oxygen during nucleation. Increase in oxygen leads to the formation of interfacial SiO2 even though the surface as monitored by RHEED rema...
In an earlier report we explored structural correlations at a liquidsolid interface with molecular dynamics simulations of a model aluminium system using the Ercolessi-Adams potential and up to 4320 atoms. Substrate atoms were pinned to their equilibrium fcc crystalline positions while liquid atoms were free to move. A direct correlation between the amount of ordering in the liquid phase and th...
The most common problem of welding dissimilar metals (DMWs) with respect to residual stresses is the differences in the coefficient of thermal expansion and heat conductivity of the two welded metals. In the present work, a CO2 continuous laser welding process was successfully applied and optimized for joining a dissimilar AISI 316 stainless steel and low carbon steel plates. The Taguchi approa...
