Intense Terahertz Excitation of Semiconductors presents the first comprehensive treatment of high-power terahertz applications to semiconductors and low-dimensional semiconductor structures. Terahertz properties of semiconductors are in the center of scientific activities because of the need of high-speed electronics. This research monograph brigdes the gap between microwave physics and photonics. It focuses on a core topic of semiconductor physics providing a full description of the state of the art of the field. _ The reader is introduced to new physical phenomena which occur in the terahertz frequency range at the transition from semi-classical physics with a classical field amplitude to the fully quantized limit with photons. The book covers a wide range of optical, optoelectronic, and nonlinear transport processes, presenting experimental results, clearly visualizing models and basic theories. Background information for future work and exhaustive references of current literature are given. A particularly valuable feature is through the discussion of various technical aspects of the terahertz range like the generation of high-power coherent radiation, optical components, instrumentation, and detection schemes of short intense radiation impulses. The book complements, for the first time in form of a monograph, previous books on infrared physics which dealt with low-power optical and opto-electronic processes. It will be useful not only to scientists but also to advanced students who are interested in terahertz research.

Terahertz technology has moved on from being a useful but expensive circuit technique, applied largely in astronomy and space science, to become a subject in its own right, with important applications - terahertz imaging in particular. Indeed, the driving force in terahertz technology is currently imaging and spectroscopy. We now have the means to obtain images and chemical information in this frequency band. The images reproduced in this volume are striking and, not surprisingly, the clinical and analytical uses are the subject of intense activity. There is still, however, no complete range of active THz electronic components, but an encouraging conclusion of the book is that THz electronics will become necessary in communications systems in the foreseeable future. Terahertz technology has come of age, and the future lies open to new, exciting science and vital applications.

Das Gebiet der Bio-Sensorik wird für die Medizin und die biologische Grundlagenforschung immer bedeutender. In diesen Bereichen ist die Untersuchung charakteristischer Eigenschaften von Membranproteinen unerlässlich, da sie die Kommunikation und Aktivität biologischer Zellen verantworten. Darüber hinaus steuern sie den Transport verschiedener Substanzen in die Zelle und eignen sich als Ziel von Medikamenten. Diese Art von Proteinen weisen charakterisitsche Resonanzen zwischen 200GHz und 2 THz auf. In dieser Arbeit wird das Design von gekoppelten plasmonischen THz-Antennen gezeigt. Diese Antennen bestehen aus hochdotiertem Germanium auf einem Siliziumsubstrat und verfügen über eine Resonanzfrequenz von 500 GHz. Sie bieten eine hohe Empfindlichkeit für dünne Schichten in einer wässrigen Lösung und eignen sich für die Charakterisierung von Proteinen im THz-Bereich. Der Entwurf dieser Antennen wird mithilfe von Finite-Elemente-Simulationen durchgeführt. Da solch ein Entwurf einen hohen Rechenaufwand umfasst, wird ein weiterer Ansatz gezeigt. Die plasmonische Antenne wird als RLC-Schwingkreis beschrieben, was Designs mit analytischen Berechnungen ermöglicht. Aufgrund dieser Berschreibung kann eine Anpassung der Impedanz zwischen Antenne und Biomolekül durchgeführt werden, wodurch die Struktur weiter optimiert wird. Neben dem THz-Bereich wird auch der Infrarot-Bereich untersucht. Dort sind Proteinbindungsprozesse zu beobachten. In dieser Arbeit wird eine neuartige Struktur untersucht, um die Brechungsindexdispersion von Proteinen zu messen. Für diese Untersuchung wird ein Array aus Silizium-Mikrosäulen analysiert. Sie zeigen eine hohe Sensitivität für sehr dünne Schichten. Die Ergebnisse dieser Arbeit zeigen, dass sich die untersuchten Sensorstrukturen für die Charakterisierung von Membranproteinen im THz- und Infrarot-Bereich sehr gut eignen. Weiterin sind sie kompatibel zu BiCMOS Prozessen und ermöglichen die kostengünstige Herstellung von Lab-on-Chip Architekturen.

The last research frontier in high frequency electronics now lies in the so-called THz (or submillimeter-wave) regime between the traditional microwave and infrared domains. Significant scientific and technical challenges within the terahertz (THz) frequency regime have recently motivated an array of new research activities. During the last few years, major research programs have emerged that are focused on advancing the state of the art in THz frequency electronic technology and on investigating novel applications of THz frequency sensing. This book serves as a detailed reference for the new THz frequency technological advances that are emerging across a wide spectrum of sensing and technology areas.
