Universal Features of Quantized Thermal Conductance of Carbon Nanotubes

Takahiro Yamamoto, Satoshi Watanabe, Kazuyuki Watanabe

The universal features of quantized thermal conductance of carbon nanotubes (CNTs) are revealed through theoretical analysis based on the Landauer theory of heat transport. The pho…

Scaling of the anomalous Hall effect in Sr $_{1 - x}$ Ca $_{x}$ RuO $_{3}$

R. Mathieu, A. Asamitsu, H. Yamada +5

The anomalous Hall effect (AHE) of ferromagnetic thin films of Sr $_{1 - x}$ Ca $_{x}$ RuO $_{3}$ (0 $\leq x \leq$ 0.4) is studied as a function of $x$ and temperature $T$ . As $x$ increases…

A spin metal-oxide-semiconductor field-effect transistor using half-metallic-ferromagnet contacts for the source and drain

S. Sugahara, M. Tanaka

We propose and theoretically analyze a novel metal-oxide-semiconductor field-effect-transistor (MOSFET) type of spin transistor (hereafter referred to as a spin MOSFET) consisting…

Polarization-dependent photoluminescence-excitation spectra of one-dimensional exciton and continuum states in T-shaped quantum wires

Hirotake Itoh, Yuhei Hayamizu, Masahiro Yoshita +5

We measured polarization-dependent photoluminescence-excitation spectra of highly uniform T-shaped quantum wires at 5 K. We attribute one peak to the 1D-exciton ground state and th…
