چکیده
|
The heterostructures of two-dimensional (2d) materials have broad application prospects in surface plasmon resonance (spr) biosensor. in order to enhance the sensitivity, we propose new a configuration of spr biosensor based on cu/au/ag-indium tin oxide (ito)-graphene/two-dimensional transition metal dichalcogenide (tmdc) hybrid structures for highly sensitive sensors. the highest angular sensitivity with 219.4°/riu for the ag-ito-ws2 is obtained. in addition, the spr biosensor can also be used to detect analytes with different refractive index. the phase sensitivity of cu-ito-mose2 structure is 30.18 times higher than that of the single cu thin film and 1.51 times higher than that of the cu-ito hybrid structure. it is believed that the spr sensor has potential application prospects in environmental monitoring, chemical examination, and biological and gas detection.
