The interaction of semiconductor surfaces with deposited metals is
very important for understanding many aspects of the behavior of
microelectronic devices. The early stages of metal-semiconductor
interface formation are amenable to analysis with surface sensitive
techniques. The most important characteristic of metal
semiconductor interface is nature of the potential barrier between
the Fermi level in the metal and the majority carrier band edge of
semiconductor of that interface. The study of metal / semiconductor
(Si) reactions are of great importance present in every
semiconductor device.The present book is an outcome of
investigations of structural, morphological, magnetic and
electrical behaviour of metal (Co, Cr, Ni) / semiconductor (Si)
system.
In the area of energy technology, we find hydrogen (1) in gaseous,
liquid, or solid hydrocarbons; (2) in nuclear fission and fusion
processes and, (3) as synthetic fuel produced by dissociation of
H2O or hydrocarbons using primary energy. The gate to use hydrogen
as a fuel opens through the storage of hydrogen. There are number
of ways of storing hydrogen but the most practical method for
onboard application is 'Metal Hydride'. Recently Zirconium based
alloys have attracted a great deal of attention for their
substantial hydrogen storage capacity. But the high stabilities of
these hydrides as indicated by their high enthalpy values make
these alloys unsuitable for hydrogen storage applications. The
present book is an outcome of the research efforts to increase the
equilibrium pressure and thus to reduce the stability of their
hydrides. Another purpose of this study is to obtain knowledge of
structural and magnetic characteristics of the alloys and relevant
hydrides.
