DOI: 10.1016/j.tsf.2020.138012
Abstract: Abstract Clear Coulomb blockade characteristics of Fe nanodots in a multiple-nanodot array were achieved. The array was fabricated in a self-assembled manner by Fe deposition between the source and drain electrodes on thermally-grown SiO2/Si substrates.… read more here.

DOI: 10.1103/physrevb.96.155405
Abstract: Charge and heat transfer through a nanoscale conductor is not only determined by the transmission properties of the electrons, but can also be strongly impacted by coupling to other degrees of freedom in the environment… read more here.

DOI: 10.1103/physrevlett.124.126804
Abstract: Magnetotransport through cylindrical topological insulator (TI) nanowires is governed by the interplay between quantum confinement and geometric (Aharonov-Bohm and Berry) phases. Here, we argue that the much broader class of TI nanowires with varying radius-for… read more here.

Abstract: If two metal nanoparticles are ultimately approached, a tunneling current prevents both an infinite redshift of the bonding dipolar plasmon and an infinite increase of the electric field in the hot spot between the nanoparticles.… read more here.

DOI: 10.7567/1882-0786/ab2cd7
Abstract: Coulomb-blockade transport via donors working as quantum dots (QDs) in Si nano-transistor channels opens new pathways for atomic-level applications, but position-control of such QDs remains challenging. Here, we demonstrate that multiple-donor cluster-QDs can be formed… read more here.
