Abstract

The hole-doped LixBC (x<1) has been theoretically predicted to exhibit superconductivity. In this report, preliminary information about the atomistic structure, thermal stability and magnetic property was presented on the single phase LixBC (x=0.5 and 1.0), using Li hydride as a starting material. The hydrogen concentration in LixBC (x=0.5) is about 0.7mass% (Li0.5BC-H0.18), and the hydrogen desorption occurs around 700K. The absence of superconductivity might originate from the modified atomistic structure, detected by Raman spectroscopy. We propose that the hydrogen concentrations can be varied for realizing superconductivity in LixBC (x<1).
