This volume presents a comprehensive examination of II-VI semiconductor materials and their application in sensors, biosensors, and radiation detectors. It focuses on the fundamental properties of compounds such as zinc oxide, cadmium telluride, and mercury cadmium telluride, detailing how their unique electronic and optical characteristics enable precise detection of various physical, chemical, and biological signals. The text systematically covers sensor design principles, fabrication techniques, and performance optimization strategies. Special attention is given to the integration of these materials into practical devices, including photodetectors, gas sensors, and medical diagnostic tools. Readers will find detailed discussions on signal transduction mechanisms, noise reduction methods, and the role of doping and nanostructuring in enhancing sensitivity and selectivity.

The content is supported by numerous schematics, data tables, and real-world application examples that illustrate the capabilities and limitations of current technologies. The book transitions into biosensing applications, exploring how II-VI semiconductors can be functionalized to detect biomarkers, pathogens, and environmental contaminants. Surface modification approaches, such as antibody immobilization and aptamer conjugation, are explained alongside the resulting improvements in detection limits. The volume also addresses the critical challenges of stability, biocompatibility, and calibration in on-field or clinical settings. Each chapter builds upon the previous one, offering a logical progression from material science to device engineering.

Researchers and engineers working with optoelectronic sensors, nuclear instrumentation, or point-of-care diagnostics will find this resource particularly valuable for understanding the interplay between material composition and sensor performance. The text maintains a neutral, factual tone throughout, avoiding speculative claims while highlighting verified advancements. A major portion of the volume is dedicated to radiation detection using II-VI compound semiconductors. It covers both direct and indirect conversion detectors, with emphasis on cadmium telluride and cadmium zinc telluride for gamma-ray and X-ray spectroscopy. Key topics include charge transport properties, polarization effects, electrode design, and signal processing electronics.

The book compares these sensors with traditional scintillator-based systems, detailing advantages such as room-temperature operation, high energy resolution, and compact form factors. Performance metrics like detection efficiency, energy linearity, and count rate capability are discussed with reference to standardized testing protocols. The text also explores emerging trends in pixelated detectors, three-dimensional sensor architectures, and hybrid systems that combine multiple transduction principles. Practical considerations for assembling readout circuits, shielding against background radiation, and minimizing electronic noise are provided in a clear step-by-step manner. The volume concludes with an overview of manufacturing scalability, cost reduction approaches, and commercial applications across industries.

It evaluates the economic feasibility of production methods such as metalorganic vapor phase epitaxy, molecular beam epitaxy, and electrodeposition. The discussion includes quality control measures, wafer processing techniques, and packaging solutions that affect long-term reliability. While the book is targeted at graduate students and specialists, its structured presentation and abundant references make it accessible to newcomers entering the field. The practical value is enhanced by data on material parameters, device geometries, and measured performance characteristics that can be directly applied to research projects or product development. Given its extensive coverage and reasonable price point, this handbook serves as a reliable reference for professionals seeking to understand or implement II-VI semiconductor-based sensor and detector technologies.
