Semiconductor Gas Sensors

• Offers an overview of resistor and non-resistor sensors
• reviews developments in gas sensors and sensing methods, including graphene based sensors and direct thermoelectric sensors
• discusses the use of nanomaterials in gas sensing
• Studies applications of semiconductor gas sensors in areas such as environmental monitoring and detecting chemical warfare agents

Semiconductor gas sensors are an important class of sensors with a broad range of applications in safety and environmental monitoring. This important book summarises recent research on principles, technologies and applications of this technology.

The book starts with an introductory review of resistor and non-resistor types of sensor, conduction mechanisms, electrode materials and electrode-oxide interfaces. The second section of the book reviews recent developments in silicon carbide and graphene-based gas sensors, wide bandgap semiconductor gas sensors, micromachined and direct thermoelectric sensors. Part three discusses the use of nanomaterials, including metal oxide nanostructures, quantum dots, single-walled carbon nanotubes and porous silicon. The final part of the book surveys key applications in environmental monitoring, detecting chemical warfare agents and monitoring gases such as carbon dioxide.

Semiconductor gas sensors is an essential reference for all those involved in gas monitoring, including the building industry, environmental engineers, defence and security specialists, as well as those researching the subject.
