Phosphorene is a new family member of two-dimensional materials. We observed strong and highly layer-dependent photoluminescence in few-layer phosphorene (two to five layers). The results confirmed the theoretical prediction that has direct layer-sensitive band gap. also demonstrated more sensitive temperature modulation than graphene MoS2 Raman scattering. anisotropic response enabled us use an optical method quickly determine crystalline orientation without tunneling electron microscopy or...
Determining the quality of Ti-6Al-4V parts fabricated by selective laser melting (SLM) remains a challenge due to high cost SLM and need for expertise in processes materials. In order understand correspondence relative density SLMed with process parameters, an optimized extreme gradient boosting (XGBoost) decision tree model was developed present paper using hyperparameter optimization GridsearchCV method. particular, effect size dataset training testing on prediction accuracy examined. The...
Chirality plays a significant role in the physical properties and biological functions of many materials, e.g., climbing tendrils twisted leaves, which exhibit chiral growth. However, mechanisms underlying growth materials remain unclear. In this paper, we investigate how Towel Gourd achieve their Our experiments reveal that have hierarchy chirality, transfers from lower levels to higher. The change helical angle cellulose fibrils at subcellular level induces an intrinsic torsion tendrils,...
Two-dimensional (2D) materials have emerged as promising candidates for miniaturized optoelectronic devices due to their strong inelastic interactions with light. On the other hand, a optical system also requires elastic light-matter control flow of Here we report that single-layer molybdenum disulfide (MoS2) has giant path length (OPL), around one order magnitude larger than from graphene. Using such OPL engineer phase front beams demonstrated, best our knowledge, world's thinnest lens...
We report a trion (charged exciton) binding energy of ∼162 meV in few-layer phosphorene at room temperature, which is nearly 1–2 orders magnitude larger than those two-dimensional (2D) transition metal dichalcogenide semiconductors (20–30 meV) and quasi-2D quantum wells (∼1–5 meV). Such large has only been observed truly one-dimensional (1D) materials such as carbon nanotubes, whose optoelectronic applications have severely hindered by their intrinsically small optical cross sections....
The control of exciton and triondynamics in bilayer MoS2 is demonstrated, via the comodulations by both temperature electric field. calculations here show that band structure changes from indirect at room toward direct nature as decreases, which enables electrical tunability K–K PL transition low temperature. As a service to our authors readers, this journal provides supporting information supplied authors. Such materials are peer reviewed may be re-organized for online delivery, but not...
The oscillatory behavior of a double-walled carbon nanotubes with rotating inner tube is investigated using molecular dynamics simulation. In the simulation, one end outer assumed to be fixed and other free. Without any prepullout tube, it interesting observe that self-excited oscillation can triggered by nonequilibrium attraction ends two tubes. amplitude increases until reaches its maximum decrease speed tube. bitube sensitive gap between walls. Numerical results also indicate...
This article investigated the microstructure of Ti6Al4V that was fabricated via selective laser melting; specifically, mechanism martensitic transformation and relationship among parent β phase, martensite (α’) newly generated phase formed in present experiments were elucidated. The primary X-ray diffraction (XRD), transmission electron microscopy (TEM) tensile test combined to discuss between α’, mechanical properties. average width each coarse columnar grain is 80–160 μm, which agreement...
