In this review, we describe recent progress made in the study of nanoparticles characterized
by scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS). Basic …

Charge states of atoms can be investigated with scanning tunneling microscopy, but this
method requires a conducting substrate. We investigated the charge-switching of individual …

Scanning tunneling microscopy and dynamic force microscopy in the noncontact mode are
used in combination to investigate the reversible switching between two stable states of a …

Strong confinement of charges in few-electron systems such as in atoms, molecules, and
quantum dots leads to a spectrum of discrete energy levels often shared by several …

Gold nanoparticles play important roles in different branches of science, such as in
nanoelectronics, nonlinear optics, biological labeling, and oxidation catalysis, among …

Individual molecules at the edges of self-assembled islands grown on Ag (111) can be
deliberately switched in their charge state with the electric field from a scanning-probe tip …

Stable and monodisperse Au nanoparticles smaller than 2 nm are easily prepared by the
reduction of HAuCl4⊙ 4H2O in DMF/H2O in the presence of a series of bidentate ligands, 2 …

Coulomb diamonds were clearly observed on single-electron transistors (SETs) fabricated
by bottom-up processes of electroless plating of Au nanogap electrodes and chemisorption …

It is well known that scanning probe techniques such as scanning tunnelling microscopy
(STM) and atomic force microscopy (AFM) routinely offer atomic scale information on the …

A single-molecule single-electron transistor (SM-SET) consisting of a π-conjugated
quinoidal-fused oligosilole derivative, Si-2, of radius 0.75 nm and heteroepitaxial spherical …
