TLDR
The present result reveals that the EDLT is an extremely versatile tool to induce electronic phase transitions by electrostatic charge accumulation and provides new routes in the search for superconductors beyond those synthesized by traditional chemical methods.Abstract:
Using a liquid gate has allowed electrically induced superconductivity in a solid specimen by means of carrier accumulation on the surface. But this phenomenon was limited to materials that became superconductors at low carrier density. It is now shown that superconductivity can be induced in a much wider range of materials by using an ionic liquid.read more

Emergent phenomena at oxide interfaces
TL;DR: Recent technical advances in the atomic-scale synthesis of oxide heterostructures have provided a fertile new ground for creating novel states at their interfaces, with characteristic feature is the reconstruction of the charge, spin and orbital states at interfaces on the nanometre scale.

Ionic Liquids at Electrified Interfaces
TL;DR: One of the advantages of RTILs as compared to their high-temperature molten salt (HTMS) “sister-systems” is that the dissolved molecules are not imbedded in a harsh high temperature environment which could be destructive for many classes of fragile (organic) molecules.

Superconducting Dome in a Gate-Tuned Band Insulator
TL;DR: A large enhancement in the transition temperature Tc occurring at optimal doping in the chemically inaccessible low–carrier density regime is revealed, indicating that the superconducting dome may arise even in doped band insulators.

Suppression of Metal-Insulator Transition in VO2 by Electric Field–Induced Oxygen Vacancy Formation
Jaewoo Jeong,Nagaphani Aetukuri,Nagaphani Aetukuri,Tanja Graf,Thomas D. Schladt,Mahesh G. Samant,Stuart S. P. Parkin +6 more
TL;DR: It is found that electrolyte gating of epitaxial thin films of VO2 suppresses the metal-to-insulator transition and stabilizes the metallic phase to temperatures below 5 kelvin, even after the ionic liquid is completely removed.

Ordering, metastability and phase transitions in two-dimensional systems
TL;DR: In this article, a new definition of order called topological order is proposed for two-dimensional systems in which no long-range order of the conventional type exists, and the possibility of a phase transition characterized by a change in the response of the system to an external perturbation is discussed in the context of a mean field type of approximation.
