Current power electronics world require semiconductor devices which
are capable of highly reliable performances under extreme
conditions of voltages and temperature. Wide band gap
semiconductors are more suitable in comparison to the traditional
semiconductors in such cases. One such semiconductor currently in
focus is SiC. This book describes the strucutral, electronic and
magnetic properties of SiC. It presents the results of coputational
studies of few intrinsic and extrinsic impurities in SiC and their
combination too. Many conclusions are found which can throw some
light on its practical usefulness. The impurities considered are,
B, Al, Ga, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn and W. We have
used first principle density functional theory with different
exchange and correlation schemes using pseudopotentials to perform
the electronic structure calculations of several defects in SiC.
The theoretical background for computation has also been described
in this book.
Gutta Percha is being used in dentistry, especially in the field of
endodontics for a very long time with lot of clinical success. This
text book describes the manufacturing of the product, its physical
and chemical nature and its various forms, used in root canal
treatment. Recent manufacturing modifications have taken this
material a step further and has made it a material of choice for
endodontists till a better replacement is found in the future. This
text book will help dental undergraduates and post graduates
understand the material better to work more efficiently with it.
This text also highlights the various techniques and equipment used
for obturating root canal systems with the help of Gutta Percha as
a root canal filling material.This material has shown excellent
clinical success and more we understand its properties the better
handling can drastically improve the success rate of the treatment
done. This is nature's gift to endodontists and is here to stay.
This text book covers a wide area of interest in digital imaging in
the field of dentistry.It deals with the history of digital imaging
in dentistry and its present scope.It covers the latest technology
used in dental imaging as well as the detailed technical know how
of each imaging portfolio.It covers various technologies like CT,
MRI, 3D CT, CBCT.It compares various imaging portfolios with each
other and gives a overall view of the various technologies
available for various treatment protocols for the patients as well
as the dentist.This text will also help the technical staff as well
as the undergraduates and postgraduates to understand their
operated machines in a better way to get the best results for the
given treatment.Digitizing dental Imaging has revolutionized the
way dentistry is surging ahead in the future.This is a dream come
true for dentists.A vision Fulfilled
