Conventional doping processes are no longer viable for realizing extreme structures, such as a δ-doped layer with multiple elements, such as the heavy Bi, within the silicon crystal. Here, we demonstrate the formation of (Bi + Er)-δ-dop...

Laying-down gold nanorods (GNRs) of a monolayer immobilized on a solid substrate was realized with a hybrid method, a combination of three elemental technologies: surface modification, electrophoresis, and solvent evaporation. The self-assembly of...
The self-assembled monolayer (SAM)-modified metallic nanoparticles (MNPs) often exhibit improved chemoselectivity in various catalytic reactions by controlling the reactants’ orientations adsorbed in the SAM; however, there have been a few example...
Polarized polymer-based light-emitting diodes (PLEDs) have been fabricated by inserting a very thin photoaligned polyimide film into the device structure. The photoaligned polyimide film was used to form a highly oriented layer of light-emitting p...

By means of scanning tunnelling microscopy and spectroscopy, we have investigated the electronic structure of Bi nanolines on clean and H-passivated Si(100) surfaces. Maps of the local density of states (LDOS) images of the Bi nanolines are presen...

The reaction of molecular oxygen with the Si(11)- 7 x 7 surface is investigated at room temperature using in situ scanning tunneling microscopy and surface stress measurements to reveal the quantitative relationship between site-specific oxygen co...
Hybrid laser annealing, i.e., a serial combination of laser exposure and furnace annealing, is demonstrated to activate Bi donors that are wire-delta-doped in Si. The photoluminescence reveals that the dense Bi atoms are activated so efficiently t...
A novel DNA base-pairing beta-hairpin peptide involving intramolecular hydrogen bonds for induction of beta-hairpin secondary structure and intermolecular complementary hydrogen bonds between thymine and diaminopyridine for molecular recognition h...
