Microscopic theory of single-electron tunneling through molecular-assembled metallic nanoparticles

, 2003
We present a microscopic theory of single-electron tunneling through metallic nanoparticles connected to the electrodes through molecular bridges. It combines the theory of electron transport through molecular junctions with the description of the ...

Slow oxidation of magnetite nanoparticles elucidates the limits of the Verwey transition

Nature Communications, 2021
The Verwey transition in magnetite has been studied for nearly eight decades since its discovery in the 1940s. Here, Kim et al. elucidate the influence of chemical doping by extremely slow oxidization process with magnetite nanoparticles, revealing why ...

Magnetic relaxation in finite two-dimensional nanoparticle ensembles

, 2003
We study the slow phase of thermally activated magnetic relaxation in finite two-dimensional ensembles of dipolar interacting ferromagnetic nanoparticles whose easy axes of magnetization are perpendicular to the distribution plane. We develop a method to
