A major showcase for the compound semiconductor community, Compound Semiconductors 2002 presents an overview of recent developments in compound semiconductor physics and its technological applications to devices. The topics discussed reflect the significant progress achieved in understanding and mastering compound semiconductor materials and electronic and optoelectronic devices. The book covers heteroepitaxial growth, quantum confined emitters and detectors, quantum wires and dots, ultrafast transistors, and various compound materials.

This volume C 1 is the first supplement volume to "Phosphor" C which was published in 1965 and covers the compounds of phosphorus. Starting with the binary species formed between phosphorus and hydrogen, the present volume deals with the neutral mononuclear compounds PH through PH ; the ions featuring the same stoichiometric composition are s covered in separate sections. PH and PH are the major initial gaseous decomposition products of PH and, thus, also 2 J intermediates in many of its gas-phase reactions. Both molecules and their ions have been thoroughly investigated by a variety of modern, high-resolution spectroscopic methods during the last three decades. The coverage of their physical, and mostly molecular, properties re presents the largest part of the first two chapters (PH and ions pp. 2 to 47; PH and ions pp. 47 2 to 111). PH is the only compound described in this volume which is thermally stable under normal J conditions. It is the phosphorus analog of ammonia, but exhibits, however, a quite different chemical behavior towards most elements and compounds. The majority of its physical, and in particular spectroscopic, properties have been determined in great detail since the sixties, partially in regard to spectroscopic investigations of the atmospheres of the outer planets.

Als im September 2015 die Grenzen Deutschlands für Flüchtlinge geöffnet wurden, stellte niemand die Frage: Wie integrationsfähig ist Deutschland? Heute ist die Willkommenskultur der ersten Monate verblasst, Ernüchterung dominiert. Ignoriert wurde damals, dass die Integrationsprobleme vieler Muslime nicht gelöst waren, als die neuen Zuwanderer kamen, von denen rund 70 Prozent aus muslimischen Ländern stammen. Der bekannte TV-Journalist Joachim Wagner kommt in seinem brisanten Buch "Die Macht der Moschee" zu dem Ergebnis, dass die kulturelle Integration in die deutsche Staats- und Gesellschaftsordnung bei der Mehrheit der Muslime gescheitert ist. Die Politik hat die tiefe Verwurzelung vieler Muslime im Islam und der von ihm geprägten Kultur unterschätzt. Angst vor islamistischem Terrorismus und der Fremdheit des Islam mindern die Integrationsbereitschaft der deutschen Zivilgesellschaft. Die Schule, die wichtigste Integrationsagentur, ist mit dem Mehr-Fronten-Kampf Integration, EU-Binnenwanderung und Inklusion überfordert. Ohne eine radikale Umsteuerung der Zuwanderungspolitik wird sich die Kluft zwischen Muslimen und Nichtmuslimen vertiefen und die Gefahr sozialer und kultureller Konflikte steigen. Joachim Wagner versucht in diesem Buch den vagen Eindruck, dass bei der Integration von Muslimen etwas schiefläuft, auf seine Substanz hin abzuklopfen. Dabei arbeitet er mit empirischen Untersuchungen, Alltagserfahrungen und Interviews. Er fragt nach den Folgen der Zuwanderung für die innere Sicherheit und die Integrationsfähigkeit unserer Gesellschaft. Mithilfe dieser Zwischenbilanzen wird das Konfliktpotenzial vermessen, das die Zuwanderung von 1,7 Millionen Muslimen seit 2011 vermutlich mit sich bringen wird. Im Zentrum des Buches stehen also folgende Fragen: Ist die kulturelle Integration der Muslime ge- oder misslungen? / Ist die kulturelle Prägung durch den Islam eine Ursache dafür, dass bei vielen Muslimen die Integration schlechter gelingt als bei Zuwanderern aus westlichen Kulturen? / Welche Rolle spielt die Zuwanderungswelle nach dem 15. September 2015 für die kulturelle Integration der Muslime? / Hat sich die Kluft zwischen muslimischer Minderheit und deutscher Mehrheitsgesellschaft vertieft? / Wie groß ist das Konfliktpotenzial der Zuwanderung nach dem 15. September 2015? / Wie viel humanitär begründete Zuwanderung ist mit der Integrationsfähigkeit der deutschen Gesellschaft vereinbar?

Scheitert die Integration am Islam?

In the first part of this volume the nitrogen-containing compounds of molybdenum are described. The Mo-N system shows that M0 N and MoN are the stable nitrides. MOlybdenum 2 metal dissolves nitrogen to some extent but only at high temperatures. To get better insight into the reactions between nitrogen and molybdenum, the solubility, diffusion, adsorption and desorption phenomena, and ion bombardment are included in the section of the Mo-N system. M0 N has a large range of homogeneity toward lower nitrogen concentrations. The black 2 hexagonal MoN has only a narrow range of homogeneity. In addition some molybdenum compounds containing nitrogen and oxygen are known. The second part contains a full description of the compounds of molybdenum with fluorine. The fluorides MoF n with n ~ 2 are metastable while those with n = 3 to 6 are stable and have been observed in the Mo-F system. Pure MoF can exist without traces of oxygen, in co nt rast 3 to earlier assumptions. MoF was unambigously prepared and characterized in 1957. Its crystal 4 structure is still unknown. MoF is often contaminated with the oxide fluoride MoOF and it is s 4 difficult to remove. Even sm all amounts affect the properties of MoF . MoF , which is liquid at s 6 room temperature and solidifies to a "plastic" crystal modification below ca. 17SC, is the most investigated of all the molybdenum fluorides.

The volume describes the chemical and physical properties of the approximately 80 known bromine compounds and ions which contain oxygen and/or nitrogen, and which may include hydrogen as well. The class of bromine-oxygen and bromine-oxygen-hydrogen compounds comprises several well-known species. Their description accounts for approximately three-quarters of the volume. The BrO radical and the BrO3 ion are the most and best studied among all binary bromine-oxygen species. BrO was recently recognized to play a role in some reaction sequences depleting the ozone concentration in the stratosphere. Bromate-ion-driven chemical oscillator systems have attracted much interest in recent decades. Thus data on single reaction steps which involve BrO3, BrO2, and the oxoacides of bromine - HBrO, HBrO2, and HBrO3 - are reviewed in detail; a comprehensive description of the oscillating systems, however, is beyond the scope of this volume. The remaining one-quarter of the volume is devoted to bromine-nitrogen and bromine-nitrogen-oxygen compounds. Bromine azide and nitrosyl bromide are the most comprehensively studied of these, accounting for almost half of this section.
