Abstract
Herein, we reported photoelectric measurements of the polyaniline decorated with bismuth sulfide (Bi2S3/PANI) nanohybrid based metal-semiconductor-metal (MSM) device in the broad electromagnetic (EM) spectrum from ultraviolet (UV) to visible (Vis) range. Bi2S3 nanorods decorated with π-conjugated polymer PANI were utilized as photodetection devices has a wide range of applications in imaging and communication. In such a novel structure, the fast electron transfer at the interface of Bi2S3 and PANI occurs, which enhances the performance of the photodetectors. Current–voltage (I–V) characteristics of the MSM photodetector device of Bi2S3/PANI nanohybrid show good ohmic nature. This photodetector device offers the highest external quantum efficiency (EQE) 104% in the UV and visible regions. It also shows the greatest detectivity of the order 1014 Jones. The photoresponsivity of the Bi2S3/PANI nanohybrid photodetector device shows 270 mAW−1 in UV region and 1270 mAW−1 in visible region at only 1 V with the minimum optical signal of 50 µWcm−2. The highest photoresponsivity of the Bi2S3/PANI nanohybrid photodetector offers 26,760 mAW−1 and 13,250 mAW−1 for the UV and visible spectra, respectively. The higher values of the LDR are 64.31 dB and 58.21 dB in the UV and visible regions, respectively, at 100 V with the lowest illumination intensity. The minimum value of NEP found in the order of 10−9 W which is the lowest value, suggests that the nanohybrid material is perfect for low-intensity photon signals. This work provides simple and effective method for the preparation of MSM photodetector technology exhibits a magnificent performance in the UV-to-Vis region.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
