Formation of silicon nanodots via ion beam sputtering of ultrathin gold thin film coatings on Si [PDF]

Nanoscale Research Letters, 2011
Ion beam sputtering of ultrathin film Au coatings used as a physical catalyst for self-organization of Si nanostructures has been achieved by tuning the incident particle energy.

Self-organized enhancement of conductivity in biological ion channels [PDF]

, 2013
We discuss an example of self-organization in a biological system. It arises from long-range ion–ion interactions, and it leads us to propose a new kind of enhanced conduction in ion channels.

Transmission electron microscopy with in situ ion irradiation [PDF]

, 2015
The macroscopic properties of materials exposed to irradiation are determined by radiation damage effects which occur on the nanoscale. These phenomena are complex dynamic processes in which many competing mechanisms contribute to the evolution of the ...

In-situ observation and atomic resolution imaging of the ion irradiation induced amorphisation of graphene [PDF]

, 2014
Ion irradiation has been observed to induce a macroscopic flattening and in-plane shrinkage of graphene sheets without a complete loss of crystallinity.

Direct observation of ion-induced self-organization and ripple propagation processes in atomistic simulations

Materials Research Letters, 2020
Patterns on sand generated by blowing winds are one of the most commonly seen phenomena driven by such a self-organization process, as has been observed at the nanoscale after ion irradiation. The origins of this effect have been under debate for decades.

Deuterium ion irradiation impact on the current-carrying capacity of DI-BSCCO superconducting tape

Nuclear Engineering and Technology, 2022
In the present work, we have irradiated the DI-BSCCO superconducting tapes with the 100 keV deuterium ions to investigate the effect of ion irradiation on their critical current (Ic).

Effect of Crystal Orientation on Self-Assembly Nanocones Formed on Tungsten Surface Induced by Helium Ion Irradiation and Annealing

Nanomaterials, 2016
The self-assembly nanocone structures on the surface of polycrystalline tungsten were created by He+ ion irradiation and then annealing, and the resulting topography and morphology were characterized using atomic force microscopy and scanning electron ...

Shape Deformation in Ion Beam Irradiated Colloidal Monolayers: An AFM Investigation

Nanomaterials, 2020
Self-assembly of colloidal monolayers represents a prominent approach to the fabrication of nanostructures. The modification of the shape of colloidal particles is essential in order to enrich the variety of attainable patterns which would be limited by

Modulating the Photoresponse Performance of Two‐Dimensional GeSe Photodetectors in Visible Region by Ion Irradiation

Advanced Electronic Materials, 2023
The 2D GeSe‐based photodetectors have exhibited ultrahigh photoresponsivity (Rλ), sensitive‐specific detectivity (D*), and large external quantum efficiency (EQE) in previous researches.
