Topologically Linked Crystals
Toru Matsuura, Masanori Yamanaka, Noriyuki Hatakenaka +2
We discovered a new class of topological crystals, namely linked rings of crystals. Two rings of tantalum triselenide (TaSe3) single crystals were linked to each other while crysta…
High quality Fe3-deltaO4/InAs hybrid structure for electrical spin injection
Marhoun Ferhat, Kanji Yoh
Single Crystalline Fe3-deltaO4 (0<=delta<=0.33) films have been epitaxially grown on InAs (001) substrates by molecular beam epitaxy using O2 as source of active oxygen. Under opti…
Dispersion and transitions of dipolar plasmon modes in graded plasmonic waveguides
J. J. Xiao, K. Yakubo, K. W. Yu
Coupled plasmon modes are studied in graded plasmonic waveguides, which are periodic chains of metallic nanoparticles embedded in a host with gradually varying refractive indices.…
Conductance of a single molecule anchored by an isocyanide substituent to gold electrodes
Manabu Kiguchi, Shinichi Miura, Kenji Hara +2
The effect of anchoring group on the electrical conductance of a single molecule bridging two Au electrodes was studied using di-substituted (isocyanide (CN-), thiol (S-) or cyanid…
Fabrication of stable Pd nanowire assisted by hydrogen in solution
Manabu Kiguchi, Kei Murakoshi
We have mechanically fabricated a Pd nanowire in solution under electrochemical potential control. A clear feature appeared in the conductance histogram when the electrochemical po…
Optical switching in graded plasmonic waveguides
J. J. Xiao, K. Yakubo, K. W. Yu
A new mechanism of longitudinal confinement of optical energy via coupled plasmon modes is proposed in chains of noble metal nanoparticles embedded in a graded dielectric medium, w…
