We measured thermal conductivity of an individual single-crystalline Bi nanowire grown by a spontaneous growth method. The measured thermal conductivity (??) for 98 nm diameter Bi nanowire is about 1.6 W/m??K at 300 K, which is much lower than that of bulk Bi (?? for bulk Bi ?? 8 W/m-K at 300 K). This indicates that the thermal conductivity of Bi nanowires is suppressed by the strong phonon boundary...
MnTe layers of high crystalline quality were successfully grown on Si(111) and Al2O3(0001) substrates by molecular beam epitaxy. We have investigated the structure, magnetic and electric transport properties of MnTe layers by using X-ray diffraction (XRD), superconducting quantum interference device (SQUID) magnetometer, physical properties measurement system (PPMS), and X-ray photoelectron spectroscopy...
