Synthesis of FeS2 and NiS2 - part 2

A continuation of the proposal number CH6699, wherein the oxygen substitution of the synthesized FeS2 2D materials will be attempted in the INS2. If successful, we expect to grow 2D FeOS which will potentially have very interested magnetic and ferro-electric properties. H2S will be used to prepare the initial Fe sulfide 2D sheets using the methods tested during proposal CH6699 followed by a short oxidation step in the vacuum. X-ray beam will be used to carry out GIXRD characterizations (measurement of the CTRs, HK maps etc.). AES and RHEED will be used for supplementary characterization necessary for atomic structure determination.
