Transition metal dichalcogenides are a diverse class of layered materials. Due to their quasi two-dimensional nature, they are a sandbox for investigating low dimensional physics, but can be doped in a variety of ways. Not only can substitutional doping occur on either the transition metal or chalcogen site, but intercalation between the layers can tune the system as well.

Here I report on the results of three transition metal dichalcogenide systems with three drastically different results. In the Copper-Platinum-Selenium system, initial results suggest two new superconductors in the ternary phase diagram. Doping platinum into TiSe2 results in an increase in the resistivity of several order of magnitude. Angle-resolved photo-emission spectroscopy shows that Platinum doping induces a pseudo gap in the system. Scanning tunneling microscopy measurements show domain wall formation. Power law fits to the resistivity suggests that the electrical transport is dominated by Luttinger liquid behavior. Finally, the intercalation of Iron into TiS2 gives rise to several magnetic features. Large bowtie magnetoresistance arises showing an increase of up to 40%. Hysteresis in magnetization shows sharp switching behavior coinciding with the bowtie in magnetoresistance. Ferromagnetic order is seen in conjunction with glassy behavior. These results are compared and contrasted to the results in FexTiS2. My results in these systems show that the depth and breadth of physical phenomena in the transition metal dichalcogenide system make it a fascinating system for investigating strongly correlated systems.
