In Situ Raman Spectroscopy of COOH-Functionalized SWCNTs Trapped with Optoelectronic Tweezers
Figure 3
Ex situ characterization of COOH-SWCNTs following deposition with optoelectronic tweezers at high peak-to-peak voltages. (a) SEM image of SWCNT bundles deposited next to a Ti/Au fiducial marker. Scale bar = 100 nm. (b) Raman spectrum of deposited SWCNT bundles showing radial breathing mode (RBM), D, and G bands; a-Si background subtracted.
