Temperature sensing performance of 2D-MoSe2 based thermistor

Present study reports the temperature sensing performance of Molybdenum Diselenide (MoSe2) based thermistor. MoSe2 has been hydrothermally synthesized and the thermistor is fabricated by drop cast method. Powder X-ray diffraction (XRD), Raman and scanning electron microscope (SEM) analysis have been used for characterizations of the prepared material. The temperature dependent sensor response shows good stability in the temperature range of 173–373K. Temperature coefficient of resistance (TCR) of the thermistor is found to be∼-0.51%/K in the temperature range of 273– 373K and it enhances to∼-1.75%/K in low temperature range (273–173K). The response and recovery time are found to be 88s and 94s in the temperature range of 273-373K respectively. This study gives a direction for the development of simple, economical and reproducible thermistor from MoSe2.
