A rendering of the experimental setup used. Light is reflected down to the nanostructure of molybdenum disulfide (yellow and teal lattice) and PZT (blue and green). Wavelengths reflecting from the surface are captured by the top detector as transmitted wavelengths pass through the PZT to the bottom detector. (Image: Hong et al.)
