| 2 | Growth of 12-inch uniform monolayer graphene film on molten glass and its application in PbI2-based photodetector显示文摘Direct growth of large area uniform graphene on functional insulating materials is essential for engineering versatile applications of graphene. However, the existing synthesis approaches can hardly avoid the generation of non-uniform multilayer graphene along the gas flow direction, affording huge challenges for further scaling up. Herein, by exploiting the molten state of soda-lime glass, we have accomplished the direct growth of large area uniform (up to 30 cm × 6 cm) graphene via a facile chemical vapor deposition route on low cost soda-lime glass. The use of molten glass eliminates the chemically active sites (surface corrugations, scratches, defects), and improves the mobility of carbon precursors, affording uniform nucleation and growth of monolayer graphene. Intriguingly, thus-obtained graphene acts as an ideal coating layer for the surface crystallographic modification of soda-lime glass, making it epitaxy substrates for synthesizing high-quality PbI2 nanoplates and continues films. Accordingly, a prototype photodetector was fabricated to present excellent photoelectrical properties of high responsivity (~ 600 on/off current ratio) and fast response speed (18 μs). This work hereby paves ways for the batch production and the direct applications of graphene glass as platforms for constructing high performance electronic and optoelectronic devices. | Zhaolong Chen Haina Ci Zhenjun Tan Zhipeng Dou Xu-dong Chen Bingzhi Liu Ruojuan Liu Li Lin Lingzhi Cui Peng Gao Hailin Peng Yanfeng Zhang Zhongfan Liu | 2019 | Nano Research2019，12，8： | 1 |
| 3 | Oxygen-assisted direct growth of large-domain and high-quality graphene on glass targeting advanced optical filter applications显示文摘Growing high quality graphene films directly on glass by chemical vapor deposition(CVD)meets a growing demand for constructing high-performance electronic and optoelectronic devices.However,the graphene synthesized by prevailing methodologies is normally of polycrystalline nature with high nucleation density and limited domain size,which significantly handicaps its overall properties and device performances.Herein,we report an oxygen-assisted CVD strategy to allow the direct synthesis of 6-inch-scale graphene glass harvesting markedly increased graphene domain size(from 0.2 to 1.8μm).Significantly,as-produced graphene glass attains record high electrical conductivity(realizing a sheet resistance of 900Ω·sq^(-1)at a visible-light transmittance of 92%)amongst the state-of-the-art counterparts,readily serving as transparent electrodes for fabricating high-performance optical filter devices.This work might open a new avenue for the scalable production and application of emerging graphene glass materials with high quality and low cost. | Bingzhi Liu Huihui Wang Wei Gu Le Zhou Zhaolong Chen Yufeng Nie Congwei Tan Haina Ci Nan Wei Lingzhi Cui Xuan Gao Jingyu Sun Yanfeng Zhang Zhongfan Liu | 2021 | Nano Research2021，14，1： | 0 |
