Ternary Quantum Dots: Synthesis, Properties, and Applications reviews the latest advances in ternary (I-III-VI) chalcopyrite quantum dots (QDs), along with their synthesis, properties and applications. Sections address the fundamental key concepts of ternary quantum dots, progress in synthesis strategies (i.e., organic and aqueous synthesis), and characterization methods (i.e., transmission electron microscopy, dynamic light scattering, etc.). Properties of ternary quantum dots are comprehensively reviewed, including optical, chemical and physical properties. The factors and mechanisms of the cytotoxicity of ternary quantum dot-based nanomaterials are also described. Since ternary chalcopyrite quantum dots are less toxic and more environmentally benign than conventional binary II-VI chalcogenide quantum dots, they are being investigated to replace conventional quantum dots in a range of applications. Thus, this book reviews QDs in various applications, such as solar cells, photocatalytic, sensors and bio-applications. Reviews fundamental concepts of ternary quantum dots and quantum dot-nanocomposites including the most relevant synthesis strategies, key properties, and characterization techniques Delves into the cytotoxicity of quantum dots looking at the factors and mechanisms that influence cytotoxicity including demonstration of cytotoxicity assays for in vitro and in vivo tests Touches on the many applications of ternary quantum dots including biomedical applications, applications in solar cells, sensing applications, and photocatalytic applications

ABSTRACT: Modified Karnaugh map for ternary logic synthesis and logic circuit realization in ternary quantum dot cellular automata (tQCA) is presented in this research article. This modified mapping technique is used for the realization of ternary proposition logic and greater minimization in ternary logic synthesis in tQCA. The comparison is made with earlier proposed ternary mapping technique for logic minimization. The tQCA logic circuit design is also described. The tQCA layout of diverse logic gates like ternary majority voter (TMV), ternary inverter (T_INV), and ternary wire (T_WIRE) circuit is explored. In case study, 3:1 tQCA multiplexer design and tQCA layout is presented.

Abstract This paper describes a Content Addressable Memory (CAM) architecture and its ternary variant called Ternary Content Addressable Memory (TCAM) using the Quantum-dot Cellular Automata (QCA). QCA is an alternative to the current integrated circuit (CMOS) paradigm based on the characteristics of confinement and mutual repulsion between electrons. It is expected to run with clocks in high frequency (in THz order), in nanometers scale and with very low energy consumption. First, this work presents the basic building blocks (1-bit memory cell, array of memory cells, ternary memory line and encoder). Then, we describe the complete TCAM and CAM architectures. Finally, the proposed architectures are tested and validated using QCADesigner simulator, attesting their functionalities. If QCA consolidates as a possible CMOS substitute, this study can impact the design of future components that uses TCAM and CAM such as routers and switches respectively.

The benefits of ionizing radiations have been largely demonstrated through many achievements of human life. Understanding the fundamental elementary interactions of ionizing radiations with material has allowed the development of various applications needed by different industries. This book draws some facets of their applications, such as hardening process for semiconductor devices, biomedical imaging by radiation luminescent quantum dots, hydrogen gas detection by Raman lidar sensor for explosion risk assessment, water and wastewater purification by radiation treatment for environment, doping by the neutron transmutation doping for the semiconductor industry, and polymerization by irradiation, which is useful for industries requiring resistant and protective coating. I wish the chapters of this book can provide some helpful information on ionizing radiation applications.

This book outlines various synthetic approaches, tuneable physical properties, and device applications of core/shell quantum dots (QDs). Core/shell QDs have exhibited enhanced quantum yield (QY), suppressed photobleaching/blinking, and significantly improved photochemical/physical stability as compared to conventional bare QDs. The core-shell structure also promotes the easy tuning of QDs’ band structure, leading to their employment as attractive building blocks in various optoelectronic devices. The main objective of this book is to create a platform for knowledge sharing and dissemination of the latest advances in novel areas of core/shell QDs and relevant devices, and to provide a comprehensive introduction and directions for further research in this growing area of nanomaterials research.
