“…Nowadays, the rapid development and implementation of Internet of Things (IoT) using new and advanced technologies have inspired researchers to develop visible-light photodetectors based on one dimensional (1D) nanomaterials 8 , 9 . Nanowires represent a distinctive category of 1D nanostructures, thoroughly investigated due to their highly anisotropic shape (diameters of 1–100 nm and lengths up to tens of micrometers), being suitable for applications in different areas such as optoelectronics, spintronics, photocatalisys, sensing, biotechnology, etc.…”

An original photodetector system based on self-connected CuO–ZnO radial core–shell heterojunction nanowire arrays grown on metallic interdigitated electrodes, operating as visible-light photodetector was developed by combining simple preparation approaches. Metallic interdigitated electrodes were fabricated on Si/SiO2 substrates using a conventional photolithography process. Subsequently, a Cu layer was electrodeposited on top of the metallic interdigitated electrodes. The CuO nanowire arrays (core) were obtained by thermal oxidation in air of the Cu layer. Afterwards, a ZnO thin film (shell) was deposited by RF magnetron sputtering covering the surface of the CuO nanowires. The morphological, structural, compositional, optical, electrical and photoelectrical properties of the CuO nanowire arrays and CuO–ZnO core–shell nanowire arrays grown on metallic interdigitated electrodes were investigated. The performances of the devices were evaluated by assessing the figures of merit of the photodetectors based on self-connected CuO–ZnO core–shell heterojunction nanowire arrays grown on the metallic interdigitated electrodes. The radial p–n heterojunction formed between CuO and ZnO generates a type II band alignment that favors an efficient charge separation of photogenerated electron–hole pairs at the CuO–ZnO interface, suppressing their recombination and consequently enhancing the photoresponse and the photoresponsivity of the photodetectors. The electrical connections in the fabricated photodetector devices are made without any additional complex and time-consuming lithographic step through a self-connecting approach for CuO–ZnO core–shell heterojunction nanowire arrays grown directly onto the Ti/Pt metallic interdigitated electrodes. Therefore, the present study provides an accessible path for employing low dimensional complex structures in functional optoelectronic devices such as photodetectors.

“…24 Except for the flexible planar substrate, 1D wearable carbon fiber fabric also was employed to directly prepare Te@TeSe NW based PDs, which were applied in the knitted PD textiles. 16 As for stretchable PD devices, Kim and co-workers presented crumpled graphene with modification of a Au nanoparticle based stretchable film; the stretchable active materials film was obtained by buckle delamination using an elastomeric prestrained very high bond (VHB, 3MTM VHBTM 4910, 3M, MN) substrate, leading to the outstanding mechanical stretchability up to 200%. 25 The stretchable PDMS substrate also has been demonstrated as a superior elastic substrate to fabricate stretchable PD devices; the direct-writing approach of the inorganic−organic hybrid NW based UV− vis−NIR NW PD array resulted in no obvious performance degradation under extreme (up to 100%) and mechanical robustness up to 100 stretching-recovery cycles.…”

Conspectus A flexible photodetector that extends unique capabilities such as deformation, adaptivity to a soft surface, mechanical stability, and high photoresponsivity compared to the rigid devices has come to prominence in telecommunication, remote sensing, medical diagnostics, image sensing, optical communication, and the biomimetic human visual system. Low-dimensional nanomaterials consisting of one-dimensional (1D) nanowires (NWs), 2D nanoplates, and heterojunctions such as quantum dot modified NWs, hierarchical 1D hybrid nanomaterials, 1D/2D composites, 2D/2D heterostructures, etc. are considered as promising photosensitive materials in designing a flexible photodetector owing to the large surface to volume ratio and mechanical suppleness along the growth direction of the 1D NWs, excellent mechanical strength, superior structural stability, fast electron mobility, and low power dissipation of 2D nanoplates, and the synergistic effect of the heterojunctions. In this Account, we present our recent progress on low-dimensional nanostructure based flexible photodetectors. First, the three components, including the soft substrate, conductive electrodes, and representative low-dimensional nanomaterials (1D NWs, 2D nanoplates, and various types of heterojunctions) required for achieving flexible photodetector are summarized. Then, the design strategies toward functional photodetectors are presented in terms of their flexibility, stretchability, transparency, and photodetector with tunable photoresponse properties. The integration concepts of the photodetector with flexible energy storage to realize independent detectivity and the field effect transistor to amplify the responsivity are also provided. Furthermore, the application examples of the flexible photodetector in the artificial visual memory system and the biomimetic eye are reviewed. Finally, we discuss the future prospects of the low-dimensional nanostructure based flexible photodetector in the field of flexible image sensing and integrated electronics.

represents the sensing pixel. However, the performance of photodetectors is the most important factor in the NIR imaging tech nology and methodology. As NIR photo detectors are being increasingly used, a high photoelectric response (responsivity, detectivity, etc.) that meets the require ments of ultraweaklight detection and realtime fast imaging is needed. There fore, research is focused on developing a promising fabrication strategy with low consumption, high resolution, and out standing performance.
