Abstract
The present invention relates to real-time impedance spectroscopy using 2d transition metal dichalcogenide material-based chemical sensor systems and methods of making and using same. Impedance approach to breakdown the resistance into multiple, measureable resistance components is used in such system. Thus, a real time impedance can be used to measure the resistance of a flake network when exposed to a gas. This change in the resistance can now be used to determine the concentration of a gas of interest, in many cases, down to a parts per trillion level. Thus, gas concentrations can efficiently and effectively determined on a more accurate level and less expensively than before.
