Researchers at Rice University make ultrasensitive conductivity measurements

Here is a very interesting report that might indeed be interesting to characterize ALD growth in-situ ultra fast at optical frequencies!

(Nanowerk News) Researchers at Rice University have discovered a new way to make ultrasensitive conductivity measurements at optical frequencies on high-speed nanoscale electronic components.The research at Rice's Laboratory for Nanophotonics (LANP) is described online in a new study in the American Chemical Society's journal ACS Nano ("Charge Transfer Plasmons: Optical Frequency Conductances and Tunable Infrared Resonances"). In a series of experiments, LANP researchers linked pairs of puck-shaped metal nanodisks with metallic nanowires and showed how the flow of current at optical frequencies through the nanowires produced "charge transfer plasmons" with unique optical signatures.
