A.M. Fogg, J.B. Claridge, G.R. Darling, M.J.Rosseinsky
TL;DR
This study synthesizes LixBC compounds through high-temperature lithium deintercalation and finds that, despite theoretical predictions, these materials do not exhibit superconductivity above 2K.
Contribution
It provides experimental synthesis and characterization of LixBC and challenges the expectation of superconductivity in these materials.
Findings
LixBC was successfully synthesized via high-temperature deintercalation.
No superconductivity above 2K was observed in the synthesized samples.
Refinement of diffraction data confirmed the structural integrity of LixBC.
Abstract
The synthesis of LixBC (x > 0.5) by high temperature Li deintercalation from LiBC is demonstrated by refinement of X-ray and neutron powder diffraction data - contrary to theoretical expectation no superconductivity above 2K is observed in these materials
