The fundamental optical excitations that are confined to a metal/dielectric interface are the surface plasmon polaritons (SPPs), as described by Ritchie. SPPs can be referred to as electromagnetic excitations existing at an interface between two media, of which at least one is conducting. Investigating spoof plasmons in a semiconductor is becoming an increasingly active area of research. The field of plasmonics deals with the application of surface and interface plasmons. It is an area in which surface plasmon-based circuits merge the fields of photonics and electronics at the nanoscale. Recently, an idea of engineering surface plasmons at lower frequencies was suggested. It was concluded in...

Semiconducting materials are widely used in several applications such as photonics, photovoltaics, electronics, and thermoelectrics, because of their optical and electro-optical features. The fundamental and technological importance of these materials is due to the unique physical and chemical properties. Over the years, numerous methods have been developed for the synthesis of high-efficient semiconductors. Moreover, a variety of approach and characterization methods have been used to study the numerous and fascinating properties of the semiconducting materials. This book collects new developments about semiconductors, from the fundamental issues to their synthesis and applications. Special attention has been devoted to electrochemical growth and characterization.
Thin-film solar cells are cheap and easy to manufacture but require improvements as their efficiencies are low compared to that of the commercially dominant crystalline-silicon solar cells. An optoelectronic model is formulated and implemented along with the differential evolution algorithm to assess the efficacy of grading the bandgap of the CIGS, CZTSSe, and AlGaAs photon-absorbing layer for optimizing the power-conversion efficiency of thin-film CIGS, CZTSSe, and AlGaAs solar cells, respectively, in the two-terminal single-junction format. Each thin-film solar cell is modeled as a photonic device as well as an electronic device. Solar cells with two (or more) photon-absorbing layers can also be handled using the optolelectronic model, whose results will stimulate experimental techniques for bandgap grading to enable ubiquitous small-scale harnessing of solar energy.
Electromagnetic metamaterials are a family of shaped periodic materials which achieve extraordinary scattering properties that are difficult or impossible to achieve with naturally occurring materials. This book focuses on one such feature of electromagnetic metamaterials—the theory, properties, and applications of the absorption of electromagnetic radiation. We have written this book for undergraduate and graduate students, researchers, and practitioners, covering the background and tools necessary to engage in the research and practice of metamaterial electromagnetic wave absorbers in various fundamental and applied settings. Given the growing impact of climate change, the call for innov...

Metamaterials have been in research limelight for the last few years owing to the exotic electromagnetic features these exhibit. With certain combinational forms of the design, these can be of prudent applications in developing antennas, filters, absorbers, sensors, energy harvesters, and many others. As such, the role of engineered mediums remains greatly important as the frequency region of operation determines the structure (of the medium(s)) to be developed – the fact that is exploited in the on-demand kind of tailoring the electromagnetic response of metamaterials. The relevant R&D investigators show keen interest in the fabrication of varieties of novel miniaturized devices that can ...
