Among the several applications that chalcogenide glasses have, one of the most recent ones is their use as sensitive materials for the detection of gases. Although many materials have been successfully tested as sensitive membrane for gas sensors, chalcogenide glasses have the advantage of not requiring high temperatures for the detection of gasses. Tellurium based membranes were the subject of many investigations during the last decade [1], but other chalcogenide systems are being studied as well [2,3].In this work, we studied the electrical properties of GeTe, SeTe and GeSe3 thin film glasses deposited by pulsed laser deposition (PLD). We measured the conductivity of the films by DC measurements as a function of the temperature. On account of these results, in future work, we will study whether the addition of other elements to the membrane will improve the electrical response of the sensor.
