The ability to detect light over a broad spectral range is central to practical optoelectronic applications and has been successfully demonstrated with photodetectors of two-dimensional layered crystals such as graphene and MoS2. However, polarization sensitivity within such a photodetector remains elusive. Here, we demonstrate a broadband photodetector using a layered black phosphorus transist...
Among the various two-dimensional semiconductors, indium selenide has recently triggered the interest of scientific community, due to its band gap matching the visible region of the electromagnetic spectrum, with subsequent potential applications in optoelectronics and especially in photodetection. In this feature article, we discuss the main issues in the synthesis, the ambient stability and t...
ZnO nanorods (NRs) were synthesized using an in situ low-temperature hydrothermal method. In order to investigate the effect of different seed layers on quality of ZnO NRs arrays, alcoholic, alkaline and acidic seed solutions were deposited by spin coating on ITO-glass substrate. Experimental results revealed that the vertically ZnO NRs obtained from monoethanolamine-based seed layer is the...
In view of their exciting optoelectronic light− matter interaction properties, plasmonic−hot-electron devices have attracted significant attention during the last few years as a novel route for photodetection and light-energy harvesting. Herein we report the use of quasi-3D large-area plasmonic crystals (PC) for hot-electron photodetection, with a tunable response across the visible and near-in...
Abstract Two-dimensional transition metal dichalcogenide (2D TMD) crystals are versatile platforms for realizing emergent optoelectronic devices. However, the ability to produce large-area 2D TMDs with spatial homogeneity and accomplish broadband photodetection by tuning operating wavelengths in photodetectors two paramount prerequisites practical applications of TMD-based photodetectors. Here,...
