For the first time, large-area CVD-grown graphene films transferred onto flexible PET substrates were used as transparent conductive electrodes in alternating current electroluminescence (ACEL) devices. The ACEL device based on a single-layer electrode has turn-on voltage of 80 V; at 480 V (16 kHz), luminance and luminous efficiency are 1140 cd/m(2) 5.0 lm/W, respectively. increases decreases with increasing stacked layers graphene, which means is best optimal choice electrode. Furthermore,...
Excellent-performance terahertz (THz) modulators based on graphene/ionic liquid/graphene sandwich structures are demonstrated. The modulation covers a broadband frequency range from 0.1 to 2.5 THz with depth of up 99% by applying small gate voltage 3 V. outstanding performance the proposed devices is due conical band structure graphene and powerful gating effect ionic liquid in proximity graphene. As service our authors readers, this journal provides supporting information supplied authors....
Nitrogen doping is a promising method to modulate the electrical properties of graphene. However, reported nitrogen-doped graphene (NG) films usually show low electron concentration and carrier mobility. In this study, we have demonstrated chemical vapour deposition NG films, where melamine was used as sole source both carbon nitrogen. The studies that nitrogen content configurations are strongly dependent on growth temperature. At temperature 990 °C, total N graphitic-N/total simultaneously...
In this study, the separator coated with reduced graphene oxide (rGO) layer is prepared via doctor blading. The lithium-sulfur (Li-S) battery rGO-coated exhibits much smaller impedance and better electrochemical performance. After rGO, initial discharge capacity can be as large 1067 mAh g−1 at 0.2 C which retain 878 after 100 cycles, reach 710 even 2 C. significant performance enhancement attributed to bi-functionality of rGO; rGO coating has unique porous structure, high conductivity...
High-quality, reduced graphene oxide (RGO) homogeneously coated LiCo1/3Ni1/3Mn1/3O2 (NCM) was synthesized by ultrasonically mixing/stirring GO and NCM in water then thermal reduction of to RGO. The composite cathode shows much higher specific capacity, better cycling stability high rate performance after being wrapped RGO, which is attributed the lower electrochemical impedance for electrode due presence It promising RGO modified be used as an excellent cathode.
A silicon-doped graphene film was synthesized by CVD using triphenylsilane as a sole carbon and silicon source. The exhibits strong p-type feature has large hole mobility of 660 cm<sup>2</sup> V<sup>−1</sup> s<sup>−1</sup>.
Abstract Although there are already many efforts to investigate the electronic structures of twisted bilayer graphene, a definitive conclusion has not yet been reached. In particular, it is still controversial issue whether tunable electrical (or transport) bandgap exists in graphene film until now. Herein, for first time, demonstrated that can be opened by combination effect twist and vertical fields. addition, we have also developed facile chemical vapor deposition method synthesize...

The electrical properties of PEI doped CVD-grown graphene transistors have been studied in detail, demonstrating that the absorbed molecular will be modified by oxygen or water during exposure ambient.
Detection of integrated circuit (IC) defects is vital in IC manufacturing. Traditional defect detection methods have relied on scanning electron microscopy and X-ray imaging techniques that are time consuming destructive. Hence, this paper we considered terahertz as a label-free nondestructive alternative. This study aimed to use convolutional neural network model (CNN) improve the performance system. First, constructed dataset analyzed it. Subsequently, new CNN structure was proposed based...

The reported flexible and transparent triboelectric generator (FTTG) can only output ultralow power density (∼2 μW cm−2), which has seriously hindered its further development application. low of FTTG is mainly limited by the material electrode structure.
