摘要
Paramagnetism in boron-containing carbon nanotubes was detected by SQUID measurements, and a g-value of 2.0020, corresponding to the free carrier spin, was observed over a wide temperature range (108-455 K). This value implies intrinsic metallic behaviour and contrasts with thermally activated semiconduction which multi-walled carbon nanotubes usually exhibit. (C) 2000 Elsevier Science B.V.
