Abstract
Hydrogen insertion into LiNbO2 was carried out using the hydrogen spillover method. The hydrogen inserted compounds, HxLiNbO2, exhibited superconducti vity below 5.5 K; this is the same critical temperature as for the delithia ted compounds, LixNbO2. Thus, LiNbO2 becomes a superconductor not only from hole doping during delithiation, but also from electron doping during hydr ogen insertion. (C) 2000 Elsevier Science Ltd. All rights reserved.
