چکیده Molybdenum disulfide (MoS 2 )/reduced Graphene Oxide (rGo)-based photodetector was fabricated based on a convenient method using a novel aligned carbon nanotube (CNT) contact configuration. With this device, one can successfully meet the challenges in device fabrication based on nano-sized 2-D materials. For this purpose, patterned CNTs were grown on a 285-nm SiO 2 /Si substrate using plasma-enhanced chemical vapor deposition. Then, thermally reduced few-layered go was drop casted on CNTs electrode followed by deposition of MoS 2 nanosheets through dispersion. The photo response of the device was investigated under laser illumination with different wavelengths (375, 405, 455, and 532) and various power intensities. Despite adding small portion of MoS 2 nanosheets, the results demonstrate an ultra-high photo responsivity of 115 mA/W at V ds = 1 V under 405-nm laser illumination, which is quite comparable with other reports.
