Enhanced Raman Scattering on Functionalized Graphene Substrates
Václav Valeš, Petr Kovaříček, Michaela Fridrichová +5
The graphene-enhanced Raman scattering of Rhodamine 6G molecules on pristine, fluorinated and 4-nitrophenyl functionalized graphene substrates was studied. The uniformity of the Ra…
Revealing the Brønsted-Evans-Polanyi Relation in Halide-Activated Fast MoS2 Growth Towards Millimeter-Sized 2D Crystals
Qingqing Ji, Cong Su, Nannan Mao +7
Achieving large-size two-dimensional (2D) crystals is key to fully exploiting their remarkable functionalities and application potentials. Chemical vapor deposition (CVD) growth of…
Colossal switchable photocurrents in topological Janus transition metal dichalcogenides
Haowei Xu, Hua Wang, Jian Zhou +3
Nonlinear optical properties, such as bulk photovoltaic effects, possess great potential in energy harvesting, photodetection, rectification, etc. To enable efficient light-current…
Designing Artificial Two-Dimensional Landscapes via Room-Temperature Atomic-Layer Substitution
Yunfan Guo, Yuxuan Lin, Kaichen Xie +21
Manipulating materials with atomic-scale precision is essential for the development of next-generation material design toolbox. Tremendous efforts have been made to advance the com…
Understanding disorder in 2D materials: the case of carbon doping of Silicene
Ricardo Pablo-Pedro, Miguel Angel Magana-Fuentes, Marcelo Videa +4
We investigate the effect of lattice disorder and local correlation effects in finite and periodic silicene structures caused by carbon doping using first-principles calculations.…
Evidence for a pressure-induced phase transition of few-layer graphene to 2D diamond
Luiz G. Pimenta Martins, Diego L. Silva, Jesse S. Smith +16
We unveil the diamondization mechanism of few-layer graphene compressed in the presence of water, providing robust evidence for the pressure-induced formation of 2D diamond. High-p…
