Ionic gating is a very popular tool to investigate and control the electric charge transport and
electronic ground state in a wide variety of different materials. This is due to its capability to …

Despite the recent discovery of superconductivity in Nd 1–x Sr x NiO 2 thin films, the
absence of superconductivity and antiferromagnetism in their bulk materials remains a …

Here, pristine and Pd-intercalated 2 H-Ta S 2 single crystals with (00 l) orientation were
grown by the chemical vapor transport technique. The superconductivity (SC) and charge …

We have performed electrochemical treatment of the van der Waals antiferromagnetic
materials FePS 3 and NiPS 3 with the ionic liquid EMIM-BF 4, achieving significant …

Intercalation of organic cations in superconducting iron selenide can significantly increase
the critical temperature (T c). We present an electrochemical method using β-FeSe crystals …

Manipulation of the carrier density of layered transition-metal dichalcogenides (TMDs) is of
fundamental significance for a wide range of electronic and optoelectronic applications …

Superconductivity with transition temperature T c above 40 K was observed in protonated
