Heterostructures have promising applications in photonics and optoelectronics, mainly due to their high electron mobility broadband photoresponse covering visible, infrared, terahertz (THz) ranges. However, it is challenging detect heterostructures definition with conventional THz techniques. Here we demonstrate a nanoscopic imaging method which capable of resolving the local response PbS-graphene based upon sophisticated near-field optical microscope. The interaction between near field...
Lead sulfide (PbS), as an excellent narrow band gap material, has a wide range of applications in short-wave infrared detection. In this study, Si/PbS photodetectors are fabricated by electrochemical deposition technique to grow PbS materials inside patterned silicon window.
