Ultrafast interlayer photocarrier transfer in graphene–MoSe_2 van der Waals heterostructure 下载免费PDF全文
We report the fabrication and photocarrier dynamics in graphene–MoSe_2 heterostructures. The samples were fabricated by mechanical exfoliation and manual stacking techniques. Ultrafast laser measurements were performed on the heterostructure and MoSe_2 monolayer samples. By comparing the results, we conclude that photocarriers injected in MoSe_2 of the heterostructure transfer to graphene on an ultrafast time scale. The carriers in graphene alter the optical absorption coefficient of MoSe_2. These results illustrate the potential applications of this material in optoelectronic devices. 相似文献
