This article reviews new superconducting phases of carbon-based materials. During the
past decade, new carbon-based superconductors have been extensively developed through …

We report here the discovery of a new aromatic hydrocarbon superconductor, Sm-doped
chrysene, with Tc∼ 5 K, and compare its behavior with those measured in the full series of …

Superconductivity in aromatic hydrocarbons doped with potassium (K) such as K 3 [picene
(PCN)] and K 3 [phenanthrene (PHN)] is found for only armchair-type polycyclic aromatic …

The chain-like organic compounds with conjugated structure have the potential to become
high temperature superconductors. Here, we show that p-quinquephenyl containing five …

As one of the simplest hydrocarbons, methane (CH4) has great potential in the research of
superconductors. However, the metallization of CH4 has been an issue for a long time …

As an alternative to Li-ion batteries, K-ion batteries have attracted attention because of the
abundant potassium reserves, low prices, and environmental friendliness of K resources. In …

We develop a two-step synthesis method—ultrasound treatment and low temperature
annealing to explore superconductivity in potassium-doped triphenylbismuth, which is …

We have performed measurements of Raman scattering, synchrotron x-ray diffraction and
visible transmission spectroscopy combined with density functional theory calculations to …

The atomic structures and electronic properties of potassium-doped phenanthrene (PHA)
with various doping levels have been investigated using first principles calculations based …
