The emerging smart power source-unitized electronics represent an utmost innovative paradigm requiring dramatic alteration from materials to device assembly and integration. However, traditional sources with huge bottlenecks on the design performance cannot keep pace revolutionized progress of shape-confirmable integrated circuits. Here, we demonstrate a versatile printable technology fabricate arbitrary-shaped, graphene-based planar sandwich supercapacitors based layer-structured film...
Interfacial integration of a shape-engineered electrode with strongly bonded current collector is the key for minimizing both ionic and electronic resistance then developing high-power supercapacitors. Herein, we demonstrated construction micro-supercapacitors (VG-MSCs) based on high-density unidirectional arrays vertically aligned graphene (VG) nanosheets, derived from thermally decomposed SiC substrate. The as-grown VG showed standing basal plane orientation grown (0001̅) substrate,...
A simple lithographic method is developed to generate large-area antireflective subwavelength structures (SWSs), in which the metal island films are used as masks. Using magnetron sputter deposition, stochastically arranged Ag islands were fabricated on Si substrates with dimensions controlled range of 50∼400nm. After reactive ion etching CF4, SWSs formed, same arrangement and density those islands. The measured reflectivity was decreased from ∼40% for polished ∼5% SWS surfaces. residual...
A type of red luminescent Sr3Al2O6:Eu2+, Dy3+ phosphor powder is synthesised by sol–gel–combustion processing, with metal nitrates used as the source ions and citric acid a chelating agent ions. By tracing formation process sol–gel, it found that necessary to reduce amount NO−3 dropping ethanol into solution for forming stable homogeneous sol–gel. Thermogravimetric Differential Scanning Calorimeter Analysis, x-ray diffractionmeter, scanning electron microscopy photoluminescence spectroscopy...
Van der Waals encapsulation of two-dimensional materials within hexagonal boron nitride (h-BN) stacks has proven to be a promising way create ultrahigh-performance electronic devices. However, contemporary approaches for achieving van encapsulation, which involve artificial layer stacking using mechanical transfer techniques, are difficult control, prone contamination, and unscalable. Here, we report on the transfer-free direct growth high-quality graphene nanoribbons (GNRs) h-BN stacks. The...
In this paper, a virtual GeSi template has been successfully fabricated by Ge filling the porous silicon (PSi) prepared electrochemical etching (EC etching). The microstructure quality measured with cross-sectional scanning electron microscopy and photoluminescence spectra reveal that PSi structure is fully filled uniformly distributed Ge. Furthermore, Raman X-ray diffraction results also show typical feature, which originates from interdiffusion during deposition. This design can be...
Abstract Melt flows in the Kyropoulos sapphire growth system include Marangoni convection and buoyancy convection. From seeding stage to final stage, both area of free surface melt height decrease zero from initial values, hence flow pattern varies during growth. To study systematically its influence on process, a non-dimensional parameter is introduced denote relative strength Temperature stream function distributions for different stages are simulated. It found that negligible early...
