Abstract Considering the effect of both buffer layer and substrate, a series ultrathin multilayered structure cathodes (UTMC) is constructed to simulate field emission (FE) process nanostructured semiconductor film (NSFCs). We find generalized FE mechanism NSFCs, in which there are three distinct modes with change applied field. Our results clearly show significant differences between conventional emitters nanofilm emitters, non-Fowler-Nordheim characteristics resonant will be inevitable for...
Using a structural search method in combination with first-principles calculations, we found lots of low energy 2D carbon allotropes and examined all possible Dirac points around their Fermi levels. Three amazing have been discovered, named as S-graphene, D-graphene E-graphene. By analyzing the topology correlations among S-, T, net W graphene graphene, that general rule is valuable for constructing are keen to possess cones electronic structures. Based on this rule, successfully designed...
The requirement of energy-storage equipment needs to develop the lithium ion battery (LIB) with high electrochemical performance. surface modification commercial LiFePO4 (LFP) by utilizing zeolitic imidazolate frameworks-8 (ZIF-8) offers new possibilities for LFP performances. In this work, carbonized ZIF-8 (CZIF-8) was coated on particles in situ growth and carbonization ZIF-8. Transmission electron microscopy indicates that there is an approximate 10 nm coating layer metal zinc...
A new type of three-dimensional (3D) NiO/ultrathin derived graphene (UDG) hybrid on commercial Ni foam (NF) for a binder-free pseudocapacitor electrode is presented. NiO nanoflakes are in situ grown by chemical bath deposition (CBD) technique the free-standing 3D UDG/NF scaffold, which first prepared simple nanocasting process consisting hydrothermal reaction and subsequent thermal transformation. The scaffold with interconnected network affords high conductivity due to graphitization degree...
Polarized photodetectors based on anisotropic two-dimensional (2D) materials display great potential applications in communications and optoelectronics. However, the existence of high dark current, low ratio, response speed limits their development. In this paper, a broadband polarization angle-dependent photodetector PdSe
Nanocubic La2Sn2O7 photocatalysts with pyrochlore structure have been successfully synthesized by a one-pot hydrothermal method. The effects of alkaline concentration, reaction time, and temperature on the structures morphologies resultant products were investigated. On basis characterization results from X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), selected area (SAED), possible growth mechanism nanocubes under conditions was proposed. absorption spectra...

Formaldehyde (HCHO) has been identified as one of the most common indoor pollutions nowadays. Manganese oxides (MnOx) are considered to be a promising catalytic material used in HCHO oxidation removal due their high activity, low-cost, and environmentally friendly. In this paper, progress developing MnOx-based catalysts for is comprehensively reviewed exploring mechanisms deactivation.

Microstructure and electrical properties of manganese oxide (MnO)‐doped (Na 0.5 Bi ) 0.92 Ba 0.08 TiO 3 (NBBT) piezoceramics were investigated in this work. X‐ray diffraction analysis shows that the suitable substitution Mn ion into B site induces lattice distortion perovskite NBBT: solution limit is at 0.3 wt% MnO. Besides, it observed sintering can be improved by adding a small amount MnO, thus increasing grain size relative density. Further, temperature dependence dielectric permittivity...

Theoretical research has predicted that ripples of graphene generates effective gauge field on its low energy electronic structure and could lead to zero-energy flat bands, which are the analog Landau levels in real magnetic fields. Here we demonstrate, using a combination scanning tunneling microscopy tight-binding approximation, with vanishing Fermi velocities will form when pseudomagnetic flux per ripple is larger than quantum. Our analysis indicates results bands one direction but not...
