文摘

Nanocrystalline graphene/graphite hybrids all carbon transparent electrodes were fabricated from photoresist with a photolithography method by the carbonization and graphitization of the aromatic molecules in the photoresist. The sheet resistance and transmittance of the hybrids transparent electrodes can be easily optimized by modulating the photoresist grid size and gridline width. The optimized hybrids were fabricated on quartz for graphene glass that exhibits excellent properties for heating device. They were also engaged on Si with a thin oxide layer by a catalyst-free and direct growth method for high-performance Schottky junction photodetectors that exhibit remarkable properties on photodetection with the photovoltage responsivity exceeding up to 10⁵ V/W under the incident light power of 0.05 μW, which make it suitable as weak-light-signal detectors. This study should be helpful on the various applications of catalyst-free, cost-effective, transparent, electrically and thermally conductive graphene.
