Magnetic measurements with atomic-plane resolution

Nature Communications, 2016
It has been predicted that electron beam probes may allow for the imaging of magnetism with atomic-scale resolution. Here, the authors demonstrate a scanning transmission electron microscopy method capable of resolving magnetic contrast from individual ...

Electron Localization Properties in Graphene [PDF]

Physical Review Letters, 2006
We study localization properties of the Dirac-like electronic states in monolayers of graphite. In the framework of a general disorder model, we discuss the conditions under which such standard localization effects as the logarithmic temperature-dependent conductivity correction appear to be strongly suppressed, as compared to the case of a two ...

Fully Hydrogenated and Fluorinated Bigraphenes–Diamanes: Theoretical and Experimental Studies

C, 2021
Diamanes are 2D diamond-like films that are nanometers in thickness. Diamanes can exist as bilayer or multilayer graphene with various modes of stacking and interlayer covalent sp3 bonds.

Electronic and magnetic properties of the interface between metal-quinoline molecules and cobalt [PDF]

, 2014
It was recently established that spin injection from a ferromagnetic metal into an organic semiconductor depends largely on the formation of hybrid interface states.

Size limits of magnetic-domain engineering in continuous in-plane exchange-bias prototype films

Beilstein Journal of Nanotechnology, 2018
Background: The application of superparamagnetic particles as biomolecular transporters in microfluidic systems for lab-on-a-chip applications crucially depends on the ability to control their motion.

Nanoribbon-ring cross perfect metamaterial graphene multi-band absorber in THz range and the sensing application

Results in Physics, 2019
In this paper, we propose a graphene nanoribbon-ring cross structure. A multi-band absorber is obtained by a simple combination of graphene nanoribbons and and graphene ring. We obtain that the theoretical absorption of three resonance wavelengths are 99.

Tuning the Electronic Properties of Mesocrystals

Small Science, 2022
Colloidal crystals are arguably one of the most promising candidates when it comes to the fabrication of nanostructured metamaterials. Especially mesocrystals show exciting new properties that emerge from their inherent directional oriented assembly. With this work, the electrical conductivity of well‐defined micrometer‐sized platinum nanocube‐based ...

Tests for Establishing Security Properties [PDF]

, 2014
Ensuring strong security properties in some cases requires participants to carry out tests during the execution of a protocol. A classical example is electronic voting: participants are required to verify the presence of their ballots on a bulletin board,
