Multilayer MoS2 shows superior performance over the monolayer for electronic devices while growth of multilayer with controllable and uniform thickness is still very challenging. It revealed by calculations that domains are thermodynamically much more favorable than ones on epitaxial substrates due to competition between surface interactions edge formation, leading accordingly a layer-by-layer pattern non-continuously distributed uncontrollable uniformity. The thermodynamics model also...
Research question: Endometrial preparation is one of the most important steps for ensuring frozen embryo transfer success. However, there no clear evidence that identifies an optimal endometrial protocol transfer. In addition, in studies assessed which were protocols, few analyzed stage and number embryos. This study compared pregnancy outcomes perinatal obstetric complications patients who transferred two cleavage-stage embryos with natural cycle those hormone replacement therapy cycle....
ConspectusTwo-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs), in particular molybdenum disulfide (MoS2), have recently attracted huge interest due to their proper bandgap, high mobility at 2D limit, and easy-to-integrate planar structure, which are very promising for extending Moore's law postsilicon electronics technology. Great effort has been devoted toward such a goal since the demonstration of protype MoS2 devices with room-temperature on/off current ratios,...
The structures and properties of one-dimensional (1D) sandwich molecular wires constructed with altering 3d transition metal (TM) the metallofullerene (TM@C60) entities, [TM&(TM@C60)]∞, are studied using density functional theory calculations. Different from bonding character insensitivity to TM previously reported 1D [TMBz]∞ [TMCp]∞ analogues, characters investigated [TM&(TM@C60)]∞ depend heavily on identity elements. In early TMs like Ti V, TM-η5 coordinate bonds favored. contrast, TM-η6...
Two-dimensional (2D) hexagonal boron nitride (h-BN) exhibits promising properties for electronic and photoelectric devices, while the growth of high-quality h-BN remains challenging. Here we theoretically explored mechanism epitaxial by using preoxidized hydrogen-annealed copper substrate, i.e., Cu2O. It is revealed thermodynamically that unidirectional nucleation can be rationalized on symmetry-matched Cu2O(111) surface rather than antiparallel Cu(111) surface. Kinetically, dehydrogenation...
Abstract Twist bilayer graphene (tBLG) with a small magic angle deviated from trivial stacking exhibits fantastic electronic properties. However, the growth of large‐area tBLG precisely controlled twist remains grand challenge due to thermodynamically unfavorable nucleation. Here, bi‐oriented step‐guided strategy is theoretically proposed for nucleation and epitaxial tBLG, where can be predetermined by orientations adjacent steps owing covalent alignment between zigzag edges. The presence...
Two-dimensional (2D) semiconducting ferromagnet Fe3GeTe2 holds great promise for advanced spintronic applications because of its gate-tunable ferromagnetic ordering at room temperature, whereas the controllable growth large-area single crystals remains very challenging due to ternary nature and variable stoichiometry inducing many competitive phases. Here, we theoretically probe mechanism selective monolayer on various epitaxial substrates. Thermodynamic analysis shows that corresponding...
The thermodynamic mechanisms as well the optimal experimental parameters of controllable growth 2D uniformly ordered boron-doped graphene have been proposed by establishing substrate-mediated phase diagrams.
The structure and stability of molecular junctions, which connect two single-wall carbon nanotubes (SWCNTs) different diameters chiral angles, (n 1, m 1)-(n 2, 2), are systematically investigated by density functional tight binding calculations. More than 100 well-aligned SWCNTs, were constructed calculated. For a highly stable junction between 1) 2) SWCNTs with opposite handedness, the number pentagon-heptagon (5/7) pairs required to build can be denoted as ∣∣n 2 - n 1∣ ∣m 1∣∣+min{∣n 1∣,...
