“…2(a)). Similar behaviors were observed in typical CDW materials such as Lu5Rh4Si10 and TlxV6S8, but the corresponding hystereses are more distinct than that in PdTeI [24,25]. In contrast, there is almost no hysteresis for the transition at T2 (inset (b) of Fig.…”

“…This observation is compatible with the presence of a CDW lattice distortion. [ 37,48–50 ] Moreover, (TEA) y MoS 2 displays a superconducting transition below 3.9 K, reaching a well‐defined zero‐resistance final state (Figure 2d). This superconducting transition span 400 mK, a value greater than the one found for perfect, homogenous superconductors.…”

When doped into a certain range of charge carrier concentrations, MoS 2 departs from its pristine semiconducting character to become a strongly correlated material characterized by exotic phenomena such as charge density waves or superconductivity. However, the required doping levels are typically achieved using ionic-liquid gating or air-sensitive alkali-ion intercalation, which are not compatible with standard device fabrication processes. Here, the emergence of superconductivity and a charge density wave phase in air-stable organic cation intercalated MoS 2 crystals are reported. By selecting two different molecular guests, it is shown that these correlated electronic phases depend dramatically on the intercalated cation, demonstrating the potential of organic ion intercalation to finely tune the properties of 2D materials. Moreover, it is found that a fully developed zeroresistance state is not reached in few-nm-thick flakes, indicating the presence of 3D superconductive paths that are severed by the mechanical exfoliation. This behavior is ascribed to an inhomogeneous charge carrier distribution, which is probed at the nanoscale using scanning near-field optical microscopy. The results establish organic-ion intercalated MoS 2 as a platform to study the emergence and modulation of correlated electronic phases.

“…A tentative explanation would involve a deficient Cs 1– x V 6 S 8 , similar to what is observed for Ba x V 6 S 8 ( x = 0.41–0.48), where T c = 2.5 K,17 perhaps increasing T c to the here observed value by deficiency on the Cs site. A minor Cs 1– x V 6 S 8 impurity could also be responsible for the magnetic anomaly at 280 K, resembling a CDW formation, as observed for isostructural Tl 1– x V 6 S 8 18…”
