One-pot chemical vapor deposition (CVD) growth of large-area Janus SeMoS monolayers is reported, with the asymmetric top (Se) and bottom (S) chalcogen atomic planes respect to central transition metal (Mo) atoms. The formation these 2D semiconductor takes place upon thermodynamic-equilibrium-driven exchange Se atoms initially grown MoSe2 single crystals on gold foils S process characterized by complementary experimental techniques including Raman X-ray photoelectron spectroscopy,...
Abstract In recent years, higher education has felt pressured to prepare its graduates for the highly competitive international market due globalization. Thus, many institutions have turned position themselves well in university rankings as a way attract best academic and student talent from all over world. Our work presents predictive model measuring performance QS world (QS-WUR). We used ten-year dataset build models with statistical machine learning algorithms contained library Caret of...
Abstract Chemical vapor deposition (CVD) allows lateral edge epitaxy of transition metal dichalcogenide heterostructures. Critical for carrier and exciton transport is the material quality nature heterojunction. Important details optical properties were inaccessible in as-grown heterostructure samples due to large inhomogeneous broadening transitions. Here we perform spectroscopy CVD grown MoSe 2 -WSe heterostructures, encapsulated hBN. Photoluminescence (PL), reflectance contrast Raman...
Abstract Optical Mie resonators based on silicon nanostructures allow tuning of light-matter-interaction with advanced design concepts complementary metal–oxide–semiconductor (CMOS) compatible nanofabrication. Optically active materials such as transition-metal dichalcogenide (TMD) monolayers can be placed in the near-field region resonators. Here, we experimentally demonstrate and verify by numerical simulations coupling between a MoSe 2 monolayer dielectric nanoresonators. Through...
Attracting the best students to top world universities has become a social phenomenon that challenges host university cities in accommodating those every year. This article presents an analysis of methodology developed by QS Best Student Cities Ranking, using set six variables and one goeal variable The goal is provide students, parents governors with allows them assess quality life different how they can improve experience international students. We present model for ranking Dataset five...
We report one-pot chemical vapor deposition (CVD) growth of large-area Janus SeMoS monolayers, with the asymmetric top (Se) and bottom (S) chalcogen atomic planes respect to central transition metal (Mo) atoms.

The multipole expansion of a nano-photonic structure's electromagnetic response is versatile tool to interpret optical effects in nano-optics, but it only gives access the modes that are excited by specific illumination. In particular study various illuminations requires multiple, costly numerical simulations. Here we present formalism call "generalized polarizabilities", which combine recently developed exact decomposition [Alaee et al., Opt. Comms. 407, 17-21 (2018)] with concept...
Chemical vapor deposition (CVD) allows lateral edge epitaxy of transition metal dichalcogenide heterostructures with potential applications in optoelectronics. Critical for carrier and exciton transport is the quality two materials that constitute monolayer nature heterojunction. Important details optical properties were inaccessible as-grown heterostructure samples due to large inhomogeneous broadening transitions. Here we perform spectroscopy at T = 4 K also 300 access transitions CVD...
Deep learning is a promising, ultra-fast approach for inverse design in nano-optics, but despite fast advancement of the field, computational cost dataset generation, as well training procedure itself remains major bottleneck. This particularly inconvenient because new data need to be generated and network needs trained any modification problem. We propose technique that allows train single neural on broad range targets without re-training. The key idea our method enrich existing with random...
Janus Monolayers In article number 2205226, Bernhard Urbaszek, Antony George, Andrey Turchanin, and co-workers present a new method to grow large-scale high-structural-quality SeMoS monolayers on Au substrates. Their high optical quality is demonstrated by magneto-optical measurements which reveal the strong exciton-phonon coupling enable an exciton g-factor of −3.3 be obtained.
