Thin zeolite films are attractive for a wide range of applications, including molecular sieve membranes, catalytic membrane reactors, permeation barriers, and low-dielectric-constant materials. Synthesis thin using high-aspect-ratio nanosheets is desirable because the packing processing advantages over isotropic nanoparticles. Attempts to obtain dispersed suspension via exfoliation their lamellar precursors have been hampered structure deterioration morphological damage (fragmentation,...
We study the effect of transversal electric-field (E-field) on electronic properties multilayer armchair-graphene-nanoribbon (AGNR). The bandgap in multilayer-AGNRs can be reversibly modulated with application E-field. At optimized widths, we obtain a semiconductor (SC) to metallic (M) and M-SC transitions. AGNR bands undergo vivid transformations due E-field, leading phenomena such as an increase electron velocity, change sign effective mass, formation linear dispersion massless Dirac...
We have investigated the adsorption of CO, NO, CO2, and NO2 gas molecules on ultra-thin graphene nanoribbons (GNRs) using density functional theory-based calculations. In both armchair zigzag GNR, stabilize at center hexagonal ring interact weakly with GNR energy in range −0.06 to −0.56 eV. The change electron states near fermi level show that pristine is more sensitive for comparison NO CO2. When dopant (B & N) vacancy defect are introduced surface, enhanced higher interaction −0.19 −0.87...
We have investigated the Fano factor and shot noise theoretically in confined region of potential well zigzag graphene nanoribbon (ZGNR). found that is approximately 1, corresponding to minimum conductivity ( σ ) for both symmetrical asymmetrical wells. The plot with respect Fermi energy appears as plateaus on sides zero energy. Moreover, a peak observed at local density states (LDOS) confirms edge system. transmission properties ZGNR are examined using standard tight-binding Green’s...
We present the results of systematic investigation into size dependent electronic and magnetic properties ultra thin graphene nanoribbons (GNRs) finite infinite length using spin polarized density functional calculation. The rectangular GNRs with width up to 1.40 nm (2.50 nm) were investigated. are found less stable in comparison larger binding energy increasing increase size. All have shown HOMO-LUMO gap which decreases oscillatory as a function width. Finite armchair is range 0.01–0.36 eV,...
