This book provides a basic understanding of new developments on semiconductor-based sensors. Written for senior undergraduate and graduate students majoring in solid-state physics, electrical engineering, and materials science and engineering, this material is also relevant to researchers in the field of sensors for gas, chemical, bio, and medical applications. It presents original theory and experimental research, featuring numerous experts in the field who review progress in semiconductor and nano-material-based sensors and discuss the latest research regarding their applications. Fields addressed include: Si-MOS based sensors, nano-material based sensors, GaN-bsed sensor arrays for nano- and pico-fluidic systems, and InN based sensors.

There has been tremendous progress lately in the field of III-nitride (GaN, AlN, InN) semiconductors and their device applications. For example, the invention of III-nitride-based blue laser diodes was the key to a new high-density data storage technology, the Blue-ray disc. Concurrently, improvements in III-nitride-based solid state light sources have led to their use in an increasing number of illumination applications, moving steadily toward the goal of general lighting. This book focuses on three emerging areas for III-nitride applications - chemical and biological sensing, energy conversion and controlled light-matter interactions - and was based on the potential for these applications to improve our quality of life, as well as the superior material properties III-nitrides offer in terms of high chemical stability, excellent biocompatibility, efficient light absorption from the complete solar spectrum and strong light-matter coupling. Topics include: chemical and biological sensing; surface and interface properties; electronic devices; energy conversion; controlled light-matter interactions; light-emitting diodes and growth and processing.

Sales of U.S. chemical sensors represent the largest segment of the multi-billion-dollar global sensor market, which includes instruments for chemical detection in gases and liquids, biosensors, and medical sensors. Although silicon-based devices have dominated the field, they are limited by their general inability to operate in harsh environments faced with factors such as high temperature and pressure. Exploring how and why these instruments have become a major player, Semiconductor Device-Based Sensors for Gas, Chemical, and Biomedical Applications presents the latest research, including original theoretical and experimental work. It also explains how these investigations have translated into applications and products.Written by experts in the field, the chapters review cutting-edge progress on semiconductor and nanomaterial-based sensors. An excellent introduction to the subject, this book is also an outstanding reference for those working on different sensor applications. It addresses various subfields, including: GaN-based sensor arrays for quick and reliable medical testingOptical sensorsWireless remote hydrogen sensing systemsMOS-based, thin-film, and nanowire-based sensorsThe wide-bandgap semiconductor sensors discussed in this book offer many advantages as replacements for silicon-based sensors, including their high chemical resistance, high-temperature operation, and blue and ultraviolet optoelectronic behaviors. Although assays exist for biomedical detection, they are limited by various factors. Nanomaterial devices, such as the sensors examined in this book, are currently the best option for moving toward fast, label-free, sensitive, and selective multiple-detection systems for biological and medical sensing applications. Providing sufficient background information and technical detail, this is an excellent resource for advanced level undergraduate and graduate students as well as researchers in gas, chemical, biological, and medical sensors.

This book provides a comprehensive summary of the status of emerging sensor technologies and provides a framework for future advances in the field. Chemical sensors have gained in importance in the past decade for applications that include homeland security, medical and environmental monitoring and also food safety. A desirable goal is the ability to simultaneously analyze a wide variety of environmental and biological gases and liquids in the field and to be able to selectively detect a target analyte with high specificity and sensitivity. The goal is to realize real-time, portable and inexpensive chemical and biological sensors and to use these as monitors for handheld gas, environmental pollutant, exhaled breath, saliva, urine, or blood, with wireless capability.In the medical area, frequent screening can catch the early development of diseases, reduce the suffering of patients due to late diagnoses, and lower the medical cost. For example, a 96% survival rate has been predicted in breast cancer patients if the frequency of screening is every three months. This frequency cannot be achieved with current methods of mammography due to high cost to the patient and invasiveness (radiation). In the area of detection of medical biomarkers, many different methods, including enzyme-linked immunsorbent assay (ELISA), particle-based flow cytometric assays, electrochemical measurements based on impedance and capacitance, electrical measurement of microcantilever resonant frequency change, and conductance measurement of semiconductor nanostructures, gas chromatography (GC), ion chromatography, high density peptide arrays, laser scanning quantitiative analysis, chemiluminescence, selected ion flow tube (SIFT), nanomechanical cantilevers, bead-based suspension microarrays, magnetic biosensors and mass spectrometry (MS) have been employed. Depending on the sample condition, these methods may show variable results in terms of sensitivity for some applications and may not meet the requirements for a handheld biosensor.
