Special Issue Information

Dear Colleagues,

New or improved nanostructured materials and devices are at the core of developments in areas such as catalysis, electrochemical energy storage or photovoltaics, as well as for the information revolution with new memory and computational concepts. Understanding the structure of these materials and devices, their defects and their response to various stimuli is essential to developing structure–property correlations and using these as the basis for a digital twin.

With the recent developments in electron microscopy, we have established unprecedented capabilities to characterize the structure and structural changes at the nanometer and atomic scale under dynamic conditions, providing new insights into reactions and physical processes by directly imaging transient structures. Moreover, microscopy techniques have been developed that provide access to new structural features or functional properties, e.g. 4D-STEM techniques as the basis for a range of characterization methods, from orientation mapping to the analysis of glasses and disordered polymers, to imaging magnetic and electric fields in materials or devices.

This Special Issue of Nanomaterials will attempt to provide an overview of these new microscopy developments and how they have been applied to develop an increasingly deep understanding in the materials sciences with a focus on energy-related applications and information technology.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.

One-dimensional (1D) nanostructures are extensively used in the design of novel electronic devices, sensors, and energy devices. One of the major challenges faced by the electronics industry is the problem of contact between the 1D nanostructure and electrode, which can limit or even jeopardize device operations. Herein, a universal method that can realize good Ohmic and mechanical contact between an individual 1D nanostructure and a tungsten needle at sub-micron or micron scale is investigated and presented in a scanning electron microscope (SEM) chamber with the synergy of an electron beam and electrical current flowing through the welded joint. The linear I‒V curves of five types of individual 1D nanostructures, characterized by in-situ electrical measurements, demonstrate that most of them demonstrate good Ohmic contact with the tungsten needle, and the results of in-situ tensile measurements demonstrate that the welded joints possess excellent mechanical performance. By simulation analysis using the finite element method, it is proved that the local heating effect, which is mainly produced by the electrical current flowing through the welded joints during the welding process, is the key factor in achieving good Ohmic contact.
