Spray-coated carbon nanotube films offer a simple and printable solution for fabricating low cost, lightweight, and flexible thin-film electronics. However, current nanotube spray inks require either a disruptive surfactant or destructive surface fun

As electrochromic polymers can switch with a high transmittance contrast in the sub-second time frame, an analytical tool to rapidly probe the electrochemically-induced optical transition is required for characterization of these materials for electr

As part of an ongoing study to quantify the imaging response of the photoelectron emission microscope (PEEM), we have investigated the effect of sample topography on PEEM contrast. Both numerical simulations and well characterized samples were used t

We present a measurement protocol that effectively eliminates both the hysteresis and the temporal drift typically observed in the channel conductance of single-walled carbon nanotube field-effect transistors (SWNT FETs) during the application of gat
