Abstract
Variable-wavelength photocurrent microscopy and photocurrent spectroscopy are used to study the photoresponse of (n, m) sorted single-walled carbon nanotube (SWNT) devices. The measurements of (n, m) pure SWCNT devices demonstrate the ability to study the wavelength-dependent photoresponse in situ in a device configuration and deliver photocurrent spectra that reflect the population of the source material. Furthermore, we show that it is possible to map and determine the chirality population within a working optoelectronic SWCNT device.
