    Carbon (Elsevier BV)  174   240 - 247 2021.04

    Corresponding author, Accepted,  ISSN  0008-6223

     View Summary

    Silicon carbide (SiC) has excellent properties such as chemical and physical stability, biocompatibility, and high thermal conductivity. However, electrical conductivity of SiC is not high enough for electrochemical applications, which has been a major challenge. Here, in order to improve the conductivity, we prepared boron-doped SiC (SiC:B) and evaluated the electrochemical properties. SiC and SiC:B were fabricated by a microwave plasma chemical vapor deposition method. Structural characterization revealed that the main phase of SiC:B is 3C–SiC where the concentration of doped boron could be controlled by tuning the growth conditions. Electrochemical properties were evaluated by cyclic voltammetry measurements, indicating that the reactivity and sensitivity of the SiC:B electrode was comparable of that of the glassy carbon electrode.

  • Weak Antilocalization and Spin Hall Effect in Pt Films Doped with Molecular Spin

    ACS Applied Electronic Materials (American Chemical Society (ACS))  2 ( 7 ) 2098 - 2103 2020.07

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  2637-6113

     View Summary

    © 2020 American Chemical Society. A high degree of tunability and versatility of organic chemistry has paved the way toward molecular engineering of electronic and spintronic devices. Here, we report molecular spin doping of a Pt film, the key material in spin orbitronics. The molecular spin doping using a monolayer of a metal terpyridine complex allows to control the interaction between the conduction electrons and localized magnetic moments in the Pt film. The interaction was probed by measuring the weak antilocalization, which demonstrates enhanced magnetic impurity scattering induced by the molecular spin doping. By measuring the spin-orbit torque generated by Pt doped with molecular spins, we found that the spin Hall effect is robust against the magnetic impurity scattering, showing that the significant spin-orbit coupling dominates the charge-to-spin conversion in Pt. These results demonstrate that the molecular spin doping paves the way to explore spin-orbitronics phenomena.

  • Surface Rashba-Edelstein Spin-Orbit Torque Revealed by Molecular Self-Assembly

    S. Haku, A. Ishikawa, A. Musha, H. Nakayama, T. Yamamoto, K. Ando

    Physical Review Applied (Physical Review Applied)  13 ( 4 ) 044069 2020.04

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  2331-7019

     View Summary

    © 2020 American Physical Society. © 2020 American Physical Society. We report the observation of a spin-orbit torque (SOT) originating from the surface Rashba-Edelstein effect. We find that the SOT in a prototypical spin-orbitronic system, a Pt/Co bilayer, can be manipulated by molecular self-assembly on the Pt surface. This provides evidence that the Rashba spin-orbit coupling at the Pt surface generates a sizable SOT, which is hidden by the strong bulk and interface spin-orbit coupling. We show that the molecular tuning of the surface Rashba-Edelstein SOT is consistent with density-functional-theory calculations. These results illustrate the crucial role of the surface spin-orbit coupling in the SOT generation, which alters the landscape of metallic spin-orbitronic devices.

  • Avian Influenza Virus Detection by Optimized Peptide Termination on a Boron-Doped Diamond Electrode

    Teruhiko Matsubara, Michiko Ujie, Takashi Yamamoto, Yasuaki Einaga, Tomo Daidoji, Takaaki Nakaya, Toshinori Sato

    ACS Sensors (American Chemical Society (ACS))  5 ( 2 ) 431 - 439 2020.02

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  2379-3694

     View Summary

    Copyright © 2020 American Chemical Society. The development of a simple detection method with high sensitivity is essential for the diagnosis and surveillance of infectious diseases. Previously, we constructed a sensitive biosensor for the detection of pathological human influenza viruses using a boron-doped diamond electrode terminated with a sialyloligosaccharide receptor-mimic peptide that could bind to hemagglutinins involved in viral infection. Circulation of influenza induced by the avian virus in humans has become a major public health concern, and methods for the detection of avian viruses are urgently needed. Here, peptide density and dendrimer generation terminated on the electrode altered the efficiency of viral binding to the electrode surface, thus significantly enhancing charge-transfer resistance measured by electrochemical impedance spectroscopy. The peptide-terminated electrodes exhibited an excellent detection limit of less than one plaque-forming unit of seasonal H1N1 and H3N2 viruses. Furthermore, the improved electrode was detectable for avian viruses isolated from H5N3, H7N1, and H9N2, showing the potential for the detection of all subtypes of influenza A virus, including new subtypes. The peptide-based electrochemical architecture provided a promising approach to biosensors for ultrasensitive detection of pathogenic microorganisms.
