To calculate the conductivity of a material having full knowledge of itscomposition is a reasonably simple task. To do the same in reverse, i.e., tofind information about the composition of a device from its conductivityresponse alone, is very challenging and even more so in the presence ofdisorder. An inversion methodology capable of decoding the informationcontained in the conductivity response of disordered structures has beenrecently proposed but despite claims of generality and robustness, the methodhas only been used with 2D systems possessing relatively simple electronicstructures. Here we put these claims to the test and generalise the inversionmethod to the case of monolayer MoS$_2$, a material whose electronic structureis far more complex and elaborate. Starting from the spectral function thatdescribes the DC conductivity of a disordered sample of a single layeredMoS$_2$ containing a small concentration of randomly dispersed vacancies, weare able to invert the signal and find the exact composition of defects with animpressive degree of accuracy. Remarkably, equally accurate results areobtained with the optical conductivity. This is indicative of a methodologythat is indeed suitable to extract composition information from different 2Dmaterials, regardless of their electronic structure complexity. Calculatedconductivity results were used as a proxy for their experimental counterpartand were obtained with an efficient quantum transport code (KITE) based on areal-space multi-orbital tight-binding model with parameters generated bydensity functional theory.
