Abstract
The aim of this paper is to explain to young students why chemoresistive metal oxide semiconductors (MOS) gas sensors are important and widely employed in many applications. The paper deals with the fundamentals principles of these devices and their continuous improvement, due to high level of compatibility with microelectronics technology and the employment of nanostructured materials as sensing interfaces. The main operating conditions and mechanisms are also described, in order to better understand the guidelines followed to improve these devices in terms of sensing performances (sensitivity, selectivity, fast response/recovery time, repeatability, and reliability) finalized to their practical applicability. Finally, we suggest a possible brief activity on how to explore gas
期刊介绍：
This journal is of a multi- and inter-disciplinary nature and covers a broad range of fields including mathematics, computer science, physics, chemistry, biology, earth sciences, and their intersection. History of science is also included within the topics addressed by the journal. The transactions of the Pelorian Academy started out as periodic news sheets containing the notes presented by the members of the Divisions into which the Academy has been and still is organized, according to subject areas. The publication of these notes for the Division (“Classe”) of Mathematical, Physical and Natural Sciences is the responsibility of the Editorial Committee, which is composed of the Director of the division with the role of Chairman, the Vice-Director, the Secretary and two or more other members. Besides original research articles, the journal also accepts texts from conferences and invited talks held in the Academy. These contributions are published in a different section of the journal. In addition to the regular issues, single monographic supplements are occasionally published which assemble reports and communications presented at congresses, symposia, seminars, study meetings and other scientific events organized by the Academy or under its patronage. Since 2004 these transactions have been published online in the form of an open access electronic journal.
