Raman scattering, invented at the end of the last pandemic, can provide a wealth of information on the fractional, magnetic, lattice and charge excitations at the heart of quantum materials and devices. As an example I will discuss how Raman provides direct evidence for coupled phonon-electron fluids in topological semimetals, helping to explain their remarkable transport mobilities. Next I will show how Raman enabled the optimization of large and local Modulation doping in 2D materials. This doping opens the door to new phases of matter as well as nanoscale electronic, spintronic, nonlinear and photonics devices. Time permitting I will discuss our efforts to use quantum materials in biosensing to help prevent the next pandemic.
