PMOS and NMOS mobility characteristics of the dual channel (strained Si/strained Ge) heterostructure have been reviewed. It is shown that the dual channel heterostructure can provide substantially enhanced mobilities for both electrons and holes. However, germanium interdiffusion from the germanium rich buried layer into the underlying buffer layer could potentially reduce the hole mobility enh...

A two-pot-one-pack waterborne crosslinking system is studied by following the and interdiffusion between polymer particles functionalized with acetoacetoxy on one hand polyethyleneimine other. FTIR spectroscopy rheological measurements are used to follow evolution of crosslinking, while pyrene excimer fluorescence analyse chains neighbouring during film formation. Both proceed slowly at room te...

Intermetallic compounds or solid solutions can form between Zr and Mo/W, in which the multiphase of diffusion may be influenced by each other. Interdiffusion kinetic data such intermetallic systems are highly demanded for material design. In this work, solid–solid couples Zr-Mo Zr-W were prepared fixture method, interdiffusion behaviors at 1300–1500 °C systematically investigated. The results s...

In this communication we propose the use of the Augmented Space Recursion as an ideal methodology for the study of electronic and magnetic structures of rough surfaces, interfaces and overlayers. The method can take into account roughness, short-ranged clustering effects, surface dilatation and interdiffusion. We illustrate our method by an application of Fe overlayer on Ag (100) surface.

We performed neutron reflectrometry ~NR) and nuclear reaction analysis ~NRA) measurements on interdiffusion of protonated and deuterated polystyrene films Covenng several orders of magnitude in time i and resolving interfacial widths w(i) between approximately 2 nm and 60 nm we found two successive time regimes with a crossover corresponding to the reptation
