Illustration of MoS2/Nanowire Structure (image) University of Rochester Caption Far-field photons excite silver nanowire plasmons. The wire plasmons propagate to the wire's distal end where they efficiently interact with the two-dimensional material semiconductor molybdenum disulfide (MoS2). The plasmons are absorbed in the MoS2 creating excitons that subsequently decay converting back into propagating photons.
