Special Semiconducting Materials in Vivid Fields (for Thermoelectrics, Integrated Circuits, Photocatalytics, Spintronic Devices, etc.), Plasmonic Solar Cell, and Photonics

Semiconducting materials are used in widely varying fields for specific applications. Therefore, they are special purpose semiconductors. Such semiconductors are described in this chapter, for example; three-dimensional semiconductor solar cell, optical semiconductor, thermoelectric semiconductors, integrated circuit purpose semiconductors. The photocatalytic semiconductors which are used to make the environment free of pollution, are also discussed. Transparent oxide semiconductors and semiconductor based spintronic devices are also explained. Spin-charge converter, spin injection materials, plasmonic solar cells, and photonic semiconductors are also elaborated. Plasmonic and photovoltaic kinds of semiconductors are introduced. Applications of plasmonic (photovoltaic) solar cells, photonic processor, photonic crystals, and superlattices are given. Future of photonics is also incorporated. Minute insight into the various topics are given through solved numerical and theoretical examples. Review questions, numerical problems and objective type questions are also given with their answers.
