Grain boundaries are the most important type of homophase solid-solid interfaces. An example of crystalline heterophase interfaces with high relevance for technological applications are semiconductor heterostructures. 

In view of the many important applications in semiconductor technology, the interaction of hydrogen with silicon surfaces has been intensively studied. Recombinative H2 desorption from Si(100)-2 x 1 follows first-order kinetics89, unusual when compared with the second-order kinetics observed for H2 desorption from Si(lll)-7 x 7. The measured activation barriers for the desorption of H2 on Si(100) range from 45 to 66 kcalmol-189 90. 

Polvimide-Metal Interfaces. Several technological applications including semiconductor packaging and metallization demand a reliable and durable adhesion properties of the metal films. In the development of multilayer devices consist of alternating layers of metal and polyimides several reliable techniques are needed to study both thin films and their interfaces. The usefulness of the nuclear scattering techniques to study the metallization and the associated interfacial elemental diffusion processes under the effects of various temperature and humidity treatments on the metal-polyimide systems, such as Al, Cu, N, and Au on Du Pont Kapton type H have already been reported (21., 22.). Only a couple of examples are presented here to illustrate the ERD application.

The first SSMS Instrument was reported by Dempster ( 2) in 1946. Hannay of Bell Laboratories was responsible for the first applications to semiconductor materials (3,4) in the mid 50 s. The technique was so promising that commercial instrumentation became available in 1960. The attractive features of the technique were complete element coverage (all elements on the periodic table could be detected) and excellent sensitivity (to 1 part per billion atomic). The two major applications of SSMS at that time were semiconductor and nuclear reactor materials — both new technologies and both enctremely impurity sensitive. The biggest disadvantage of the technique, although not clearly realized at the time, was lack of quantitation. 

Both AsHy and SbH3 oxidize readily to the trioxide and water, and similar reactions occur with S and Se. ASH3 and SbH3 form arsenides and antimonides when heated with metals and this reaction also finds application in semiconductor technology e.g. highly purified SbHy is used as a gaseous n-type dopant for Si (p. 332).

Semiconductor nanoparticles and QDs are widely used in various fields such as luminescent biolabels [150-152] and have been demonstrated as components in regenerative solar cells [153-155], optical gain devices [24] and electroluminescent devices [23, 156, 157]. DMS have applications in spin-based electronics technologies, or spintronics [158-161]. Spintronic devices such as magnetic-optic switches, magnetic sensors, spin valve transistors and spin LEDs can be activated by implanting ferromagnetic Mn, Ni, Co and Cr in semiconductors [162-165]. Some of the applications of semiconductor nanoparticles or QDs have been explained in this section.
