Insulator Material Deposited with Molybdenum Disulphide Prospective for Sensing Application.

Two-dimensional molybdenum disulfide (MoS) exhibits interesting properties for applications in micro and nano-electronics. The key point for sensing properties of a device is the quality of the material's surface. In this study, MoS layers were deposited on polymers by pulsed laser deposition (PLD). This process was monitored by a mass quadrupole spectrometer to record the emissions of MoS and evaluate the amount of molybdenum and sulfur compounds generated. The changes in laser parameters during the PLD strongly affect the properties of the formed MoS film. The exploration of the composition and structure of the films was followed by Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR), Atomic Force Microscopy (AFM), and mass quadrupole spectrometer (MQS). The possible application of the fabricated composite as a sensor is preliminarily considered.
