AbstractBy structural and analytical TEM and scanning electron microscopy experiments we show thatatomically-resolved structural characterization of oxidation-sensitive two-dimensional material isstrongly hindered when thefinal step of the preparation process, the transfer to the TEM grid, isperformed with a wet etching method involving bases or acids, interacting with the highlyreactive sample surface. Here we present an alternative polymer-assisted and mechanical-exfoliation-based sample preparation method and demonstrate it on selected oxidation-sensitivetransition metal phosphorus trisulfides and transition metal dichalcogenides. The analysis,obtained from the samples prepared with both of the methods clearly show that oxidation is theorigin of discrepancy, the oxidation during thefinal preparation step is strongly reduced onlywhen the new method is applied, and atomically-resolved structural characterization of thepristine structures is now possible.dc.description.abstract
