This revised and expanded edition of the first comprehensive
introduction to the rapidly-evolving field of spintronics covers
ferromagnetism in nano-electrodes, spin injection, spin
manipulation, and the practical use of these effects in
next-generation electronics. Moreover, the book now also includes
spin-based optics, topological materials and insulators, and the
quantum spin Hall effect.
As the first comprehensive introduction into the rapidly evolving
field of spintronics, this textbook covers ferromagnetism in

This book, featuring the most comprehensive treatment of
Josephson junctions ever published, describes
superconductor/two-dimensional-electron-gas (2DEG) structures,
providing a better understanding of their transport properties. It
also discusses the control of junctions using gate electrodes or
injection currents, and the physical effects observed in these
junctions.
The present book covers the transport properties of
superconductor/two dimensional electron gas Josephson junctions.
Starting with the basic el ement, a superconductor/two dimensional
electron gas interface, phase co herent Andreev reflection in
hybrid Josephson junctions is introduced and further on,
multiterminal structures are discussed. Special care is taken on
explaining the underlying theoretical concepts related to the
transport mech anisms. Employing a two dimensional electron gas in
a semiconductor as a normal conductor opens up the possibility to
observe effects not found in purely metallic junctions. One example
is the light sensitivity of the semi conductor, which has a direct
impact on the supercurrent in the Josephson junction. Many of the
effects reported here rely on the fast technological progress in
the epitaxial growth of III V semiconductor heterostructures. By
using these layer systems, fascinating quantum effects have been
found. Two examples out of many are the quantized conductance in a
point contact and electron optics using ballistic electron beams.
By combining heterostructures with su perconductors, many of the
effects found in purely semiconductor systems can in a sense, be
transferred to the superconducting state. A prominent example is
the quantization of the critical current in a superconducting
quantum point contact.
