Question
This scientist conceptualized that a sheet of graphene could be rolled up into a nanotube and demonstrated its semiconducting properties. For 10 points each:
[10h] Name this MIT nanotechnologist known as the "queen of carbon science." Her spouse of the same surname discovered the splitting of energy bands in asymmetric crystals.
ANSWER: Mildred Dresselhaus [or Mildred Spiewak; or Millie in place of Mildred]
[10m] Dresselhaus mapped the vibrational modes of carbon nanotubes using a spectroscopy method named for this type of inelastic scattering, in which laser light induces Stokes and anti-Stokes shifts.
ANSWER: Raman (RAH-man) scattering [or Raman effect; or Raman spectroscopy]
[10e] Dresselhaus also designed low-energy thermoelectric materials that could be used to absorb waste amounts of this quantity. The change in energy equals this quantity plus work.
ANSWER: heat [prompt on q]
