However, 2D materials were only produced on limited archetypal substrates by chemical vapor deposition approaches. Reliable after-growth transfer techniques, that do not produce cracks, contamination, and wrinkles, are critical for layering 2D materials onto arbitrary substrates. Here we show that, by incorporating oxhydryl groups-containing volatile molecules, the supporting films can be deformed under heat to achieve a controllable conformal contact, enabling the large-area transfer of 2D films without cracks, cNature communications4409https://www.ebi.ac.uk/biostudies/studies/S-EPMC9338253biostudies-literatureLarge-area transfer of two-dimensional materials free of cracks, contamination and wrinkles via controllable conformal contact.PMC9338253ZhuoHu ZWang FZhang RWei YZhao YJia KWu HLiu WLiao JSun LWang MLiu ZZheng LWang WWang XSong YZou WYang JLi FYan RChang ZXie QPeng HHu JFang TZhang YMao BZhong HGao XLin LLu QYin JfalseLarge-area transfer of two-dimensional materials free of cracks, contamination and wrinkles via controllable conformal contact.The availability of graphene and other two-dimensional (2D) materials on a wide range of substrates forms the basis for large-area applications, such as graphene integration with silicon-based technologies, which requires graphene on silicon with outperforming carrier mobilities.
