Description
This textbook presents a comprehensive theoretical analysis of the physics underlying semiconductor materials used in gas sensing applications.
Beginning with the fundamentals of quantum mechanics and solid-state physics, the text systematically explores the physical principles and operational mechanisms of chemoresistive sensors. Through an innovative approach and a depth of coverage not found in existing literature, it offers an advanced and up-to-date treatment of sensor physics.
The content is primarily designed for students enrolled in the Sensors: Physics and Technology course within the Master s Degree Program in Physics at the University of Ferrara (UNIFE). However, it also serves a broader academic audience, including Ph.D. candidates, research fellows, and researchers in solid-state physics, particularly those specializing in gas sensing and chemoresistive sensors based on semiconductor materials.
Introduction.- Basics of Quantum Mechanics.- Introduction to Solid State Physics.- Electrons in a Weak Periodic Potential.- Semiconductors.- The p n junction.- Metal oxide MOX Gas Sensors.- Sensors Fabrication.- Temperature and Humidity sensors.- Measurement setups and applications.
Cesare Malagù was born in 1974. He has been coordinating the sensors group at the University of Ferrara since 2010 and is an associate professor since 2016. His research is based on modeling of transport phenomena in nanostructured semiconductors. His expertise regards thick-film gas sensors applied to environmental monitoring and cancer screening. His h-index is 40. He has more than 100 papers in peer reviewed journals. He is on the editorial board of several journals.
Giulia Zonta was born in 1988. She is a researcher in Physics at the Sensor Laboratory of the University of Ferrara. She works in the field of semiconductor physics, in the research and development of nanostructured chemoresistive gas sensors, particularly for medical applications. She is also a co-founder of SCENT S.r.l., a company born from university research focused on the identification of tumor biomarkers in human body fluids, aimed at developing non-invasive preventive screening devices based on gas sensor technology.
