Abstract
We report a simple, efficient and versatile method for assembling metal oxide nanomaterial-graphene core-shell structures. An ultraviolet photodetector fabricated from the ZnO nanoparticle-graphene core-shell structures showed high responsivity and fast transient response, which are attributed to the improved carrier transport efficiency arising from graphene encapsulation.
摘要
我们报道了一种简单、高效、通用的方法，用于组装金属氧化物纳米材料-石墨烯核壳结构。由 ZnO 纳米粒子-石墨烯核壳结构制备的紫外光探测器表现出高响应率和快速瞬态响应，这归因于石墨烯封装提高了载流子输运效率。
