Vapour-liquid-solid growth of ternary Bi2Se2Te nanowires.
Nanoscale research letters 9:1 (2014) 127
Abstract:
: High-density growth of single-crystalline Bi2Se2Te nanowires was achieved via the vapour-liquid-solid process. The stoichiometry of samples grown at various substrate temperatures is precisely determined based on energy-dispersive X-ray spectroscopy, X-ray diffraction, and Raman spectroscopy on individual nanowires. We discuss the growth mechanism and present insights into the catalyst-precursor interaction.Ultrahigh Anomalous Hall Sensitivity in Co/Pt Multilayers by Interfacial Modification
Applied Physics Express The Japan Society of Applied Physics 103007:6 (2013)
Abstract:
A large enhancement of anomalous Hall sensitivity (Sv) by metal/oxide interfacial modification is obtained in a MgO/[Co/Pt]3/MgO multilayered structure. The values of Sv are increased to 8363 V/A·T by CoO insertion and 2261 V/A·T by Pt insertion, while Sv is approximately 1000 V/A·T in normal Hall semiconductor sensors. Microstructural analysis shows that the crystal orientation of [Co/Pt]3 multilayers is improved, and the oxygen concentration is largely changed by introducing an ultrathin CoO layer at metal/oxide interfaces, leading to a large increment of Sv.Nonvolatile full adder based on a single multivalued Hall junction
SPIN World Scientific Publishing (2013)
Abstract:
Multivalued logic devices are promising candidates for achieving high-density, low-power memory and logic functionalities. We present a ferromagnetic multilayer Hall junction device with four distinct resistance - and thus logic - states. The states can be encoded as a quaternary bit and decoded into two binary bits. We demonstrate a nonvolatile full adder that is based on a single Hall junction, the extraordinary Hall balance. The device can be easily integrated into complex logic circuits for logic-in-memory architectures.Effect of interfacial structures on anomalous Hall behavior in perpendicular Co/Pt multilayers
