Journal ArticleDOI
The effect of heat treatment on the structural properties of electron-beam-evaporated SnO2 films
TL;DR: In this article, the effect of substrate temperature and post-deposition annealing temperature on the structural properties of the SnO 2 films for gas sensor application was studied, and it was observed from X-ray diffraction (XRD) results that the films deposited at lower substrate temperatures are amorphous and become polycrystalline SnO at 350 °C.
Journal ArticleDOI
E-beam deposited SnO2, Pt SnO2 and Pd SnO2 thin films for LPG detection
TL;DR: In this article, the electron-beam evaporation method was used to deposit undoped and Pt (or Pd) doped SnO 2 thin films, and the optimum parameters for film growth and sensor operation were identified for LP gas detection.
Journal ArticleDOI
Response study of electron-beam evaporated thin-film tin oxide gas sensors
TL;DR: In this article, the response of thin-film SnO 2 gas sensors is studied for various operating temperatures and reducing gas ambients, and it is observed that the response follows a power-law relationship with the exponent value always remaining less than one at higher concentrations of reducing gas.
Journal ArticleDOI
Analogy between electrical and structural properties of electron-beam-deposited SnO2
TL;DR: In this article, the electrical properties of electron-beam-evaporated SnO2 films were studied under various evaporation and annealing conditions, and the long-term stability of these films was then studied under sensor operating conditions to determine the deposition conditions for gas sensor applications.
Journal ArticleDOI
PC Based Simple ac Hall Measurement System
TL;DR: In this article, the authors describe the development of PC based ac-ac and dc-ac Hall measurement setup using the same circuit, which is fully computer controlled and the user's interference is limited to only turning on and off the magnetic field and its polarity.
