Efficient Green Emission from Edge States in Graphene Perforated by Nitrogen Plasma Treatment
N N Kovaleva, D Chvostova, Z Potůček +10
Plasma functionalization of graphene is one of the facile ways to tune its doping level without the need for wet chemicals making graphene photoluminescent. Microscopic corrugation…
Non-Volatile Superconductivity in an Insulating Copper Oxide Induced via Ionic Liquid Gating
Xinjian Wei, Hao-bo Li, Qinghua Zhang +19
Manipulating the superconducting states of high-T_c cuprate superconductors in an efficient and reliable way is of great importance for their applications in next-generation electr…
Optical Transistor for an Amplification of Radiation in a Broadband THz Domain
Kristian Hauser A. Villegas, Fedor V. Kusmartsev, Y. Luo +1
We propose a new type of optical transistor for a broadband amplification of THz radiation. It is made of a graphene--superconductor hybrid, where electrons and Cooper pairs couple…
Shedding light on topological superconductors
K. H. A. Villegas, V. M. Kovalev, F. V. Kusmartsev +1
We propose an optical approach to monitor superconductors in conjunction with a normal metal layer. Effectively such a hybrid system represents a resonator, where electrons are str…
Spin-orbital polarons in electron doped copper oxides
Anna Kusmartseva, Heshan Yu, Kui Jin +1
Present work demonstrates the formation of spin-orbital polarons in electron doped copper oxides, that arise due to doping-induced polarisation of the oxygen orbitals in the CuO$_2…
Bridging the Terahertz gap for chaotic sources with superconducting junctions
D. R. Gulevich, V. P. Koshelets, F. V. Kusmartsev
We observe a broadband chaotic signal of Terahertz frequency emitted from a superconducting junction. The generated radiation has a wide spectrum reaching 0.7 THz and power suffici…
