Optical band-gapDensity of statesElectron injection, Hole-to-electron effective mass ratioThe effect of reduced graphene oxide (rGO) on the performance of rGO/TiO2 composite-based dye-sensitized solar cells (DSSCs) is studied. rGO was mixed with TiO2 in an aqueous solution at different mass ...
The two synthesized materials (functionalized reduced graphene oxide and functionalized reduced graphene oxide decorated with silver nanoparticles) exhibited a 65% and 52% band gap decrease respectively, compared to graphene oxide. Moreover, both materials were soluble in organic solvents at high ...
We report broadband visible photoluminescence from solid graphene oxide, and modifications of the emission spectrum by progressive chemical reduction. The data suggest a gapping of the two-dimensional electronic system by removal ofπ-electrons. We discuss possible gapping mechanisms, and propose that ...
The electrical transport property of the reduced graphene oxide (rGO) thin-films synthesized from defective GO through thermal treatment in a reactive ethanol environment at high temperature above 1000 °C shows a band-like transport with small thermal activation energy (Ea~10 meV) that occurs...
Photonic band gap materials have the ability to modulate light. When they can be dynamically controlled beyond static modulation, their versatility improves and they become very useful in scientific and industrial applications. The quality of photonic band gap materials depends on the tunable wavelength...
Fe3O4 nanoclusters anchored on porous reduced graphene oxide (Fe3O4@rGO) have been synthesized by a one-step hydrothermal route, and then ball milled with LiBH4 to prepare a hydrogen storage composite with a low onset dehydrogenation tem... - 《Rsc Advances》 被引量: 0发表: 2018年 Multic...
The corresponding gap states are labeled with arrows. XRD patterns of the perovskite films prepared on NiOx substrates are shown in Fig. 3a. The FAMA film grown on the L-NiOx film shows strong diffraction peaks from (110) and (220) facets, indicating a pure phase and high crystallinity of...
Highly Hydrogenated Graphene through Microwave Exfoliation of Graphite Oxide in Hydrogen Plasma: Towards Electrochemical Applications Hydrogenated graphenes exhibit a variety of properties with potential applications in devices, ranging from a tunable band gap to fluorescence, ferromagnet...

Such expectations are distinctly different from those in covalent amorphous semiconductors such as amorphous hydrogenated silicon (a-Si:H), where mobility in amorphous states is largely reduced from that of the crystalline state due to CBM and VBM being formed by the sp3 hybrid orbitals (Fig. 1.3...
Closely oriented antenna elements will lead to a high coupling between the antenna elements that have to be reduced by the proper orientation of the antenna after a very proper analysis on how exactly the antenna elements could be placed. To provide better isolation between the individual elements...
