Terahertz (THz) electromagnetic waves are attractive for use in nondestructive and biocompatible sensing applications. Thermal sensors are widely used for THz detection owing to the small photon energies of THz radiation, where this requires material

We developed high-yield green fabrication of colloidal silicon quantum dots (QDs) only by low-temperature treatment of porous silicon (PSi) flakes in a reactive organic solution. Heat treatment at ∼50 °C of the PSi flakes in unsaturated hydrocarbo

Recent topics of application studies on porous silicon (PS) are reviewed here with a focus on the emissive properties of visible light, quasiballistic hot electrons, and acoustic wave. By exposing PS in solvents to pulse laser, size-controlled nc-Si

Most of the highly efficient luminescent silicon nanocrystals (SiNCs) reported to date consist of organically capped silicon cores. Here, we report a method of obtaining Si/SiO2 core/shell nanoparticles emitting at a peak energy of 1.5 eV with very h

BACKGROUND: Sexual imprinting is important for kin recognition and for promoting outbreeding, and has been a driving force for evolution; however, little is known about sexual imprinting by auditory cues in mammals. Male mice emit song-like ultrasoni

Male mice emit ultrasonic vocalizations (USVs) towards females during male-female interaction. It has been reported that USVs of adult male mice have the capability of attracting females. Although the waveform pattern of USVs is affected by genetic b

Epitaxial growth of yttria-stabilized zirconia (YSZ) thin film on through-hole-type porous silicon [tht-PSi(001)] with vertical pores penetrating from the surface to the back side of the Si(001) substrate was achieved. The inplane and out-of-plane la

Nanostructured porous silicon (PS) shows varied tunable functions leading to diversification of silicon technology. Among these functions, the emissions of photon, electron, and sound relate to the optical, electrical, and thermal properties of PS, r
