Abstract

We warmly thank all the colleagues who have enthusiastically participated in the project of this Special Issue on “2D Ultra-Thin Carbon Films”, considering a globally unfavorable context characterized by (i) a myriad of publication options; (ii) strong pressure, by the highly competitive research (and researcher) funding and evaluation system, to publish in high impact factor journals, specifically for topics of worldwide interest; and (iii) all sorts of restrictions imposed by the sanitary crisis [...]

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations
Between 2015 and 2020, the number of published scientific articles per year which were indexed in Scopus and which were referring to 2D materials in their abstract has more than doubled, increasing from ~3400 to ~7300
The Materials Research Society will organize a symposium focusing on 2D materials during the 2021 Virtual MRS Spring Meeting and Exhibit (Symposium NM07-Beyond Graphene 2D Materials— Synthesis, Properties and Device Applications) following the success of similar symposia at the 2019 and 2020 MRS Fall meetings. 2D materials get a dedicated journal since 2014, and a European experimental pilot line devoted to 2D materials was just launched in January 2021 as an initiative of the Graphene Flagship

Summary

Introduction

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. It was recently shown that hot filament CVD-promoted hydrogenation processes can be successfully used to induce the partial or full sp2 to sp3 conversion of carbon atom hybridization in 2D graphenic systems at low pressure and at low temperature to synthesize 2D crystalline sp3-bonded carbon materials [7,8,9,10,11]. These results open the door to mass production of a variety of stable 2DC materials such as diamanes, diamanoids, and diamanoid/graphene hybrids (including TBG configurations), merely by changing the type of graphenic 2DC to start with (from coherently stacked 2LG to few-layer graphene).
