High-temperature superconductivity in potassium-coated multilayer FeSe thin films

Is the most effective weight-loss strategy really that hard? Users should refer to the original published version of the material for the full abstract. The present report would lead to intensive researches to further increase Tc by changing the number of atomic layers, the amount of doped electrons and the species of supercnoductivity.

The ultrathin high-Tc superconductor would effectively contribute to the significant down-sizing and consequent high-density integration in electric circuits, leading to the realization of future-generation electronic devices with high energy-saving and ultrahigh-speed operation.

Feng Physical review letters It is based on the external photoelectric effect predicted by Einstein. N ov 2 01 8 Topological quantum states of matter in iron-based superconductors: Semantic Scholar estimates that this publication has 76 citations based on the available data.

Citation Statistics 76 Citations 0 20 40 In order to overcome these problems, it is definitely necessary to develop a new superconductor with higher- Tc, that can be fabricated into a thin film. Recent significant improvement of the energy resolution enables the precise investigation of superconducting electrons. Remote access to EBSCO’s databases is permitted to patrons of subscribing potassiu-coated accessing from remote locations for personal, non-commercial use.

The responsible substance formed by Potaswium-coated under high pressure, may be considered as a compound with H3S stoichiometry creating multilayre impressive network with hydrogens. Open Journal of Physical ChemistryVol. The superconducting transition temperature is tuned by introducing electrons by depositing potassium atoms orange circles on the surface This finding not only provides an ideal platform for investigating the mechanism of superconductivity in fexe two-dimensional system, but also paves the way for the development of next-generation nano-scale superconducting devices.

This method has an advantage in growing a high-quality single crystal film.

Here, we demonstrate that deposition of potassium onto FeSe films markedly expands the accessible doping range towards the heavily electron-doped region.

We will focus on the hydrogen bonding between sulfur and hydrogens demonstrating a symmetrical arrangement. Superconductivity at 38 K at an electrochemical interface between an ionic liquid and FeSe0. Nature Materials Publication Date: It has been shown that the recently discovered sulfur trihydride H3S can be considered as a superconductor with a transition temperature Tc of Kelvin K at GigaPascals GPa.

Tuning the band structure and superconductivity in single-layer FeSe by interface engineering. The established superconductivity occurs via the formation of a molecular system with sulfur atoms arranged on a body-centered cubic lattice.

The researchers have clearly shown how the superconductivity is emerged, enhanced and controlled in atomically thin FeSe films.

We also discuss the superconductivity of related phosphorus hydrides and focus on the stability and geometrical differences with respect to the H3S potassium-coahed.

A new frontier for superconductivity. While the Tc achieved in this study K is still lower than that of the cuprate high-Tc superconductors highest Tc?

The present result would also widen the range of both basic and applied researches on superconductivity, because the Tc of K achieved in the present study is high enough to keep the superconducting state by using a closed-cycle-gas-type cooling system without liquid helium.

However, remote access to EBSCO’s databases from non-subscribing institutions is not allowed if the purpose of the use is for commercial gain through cost reduction or avoidance for a non-subscribing institution.

From concepts to material realization Ning HaoJiangping Hu It has also been a big challenge to realize the high-density integration of superconductors into electronic devices. We also found a marked increase in the magnitude of the superconducting gap on decreasing the FeSe film thickness, indicating that the interface plays a crucial role in realizing the high-temperature superconductivity.

However, the difficulty in controlling the carrier density and the number of FeSe layers has hindered elucidation of this problem.
