In addition to its newly published data-acquisition handbook, Keithley Instruments has also published a free-of-charge handbook on nanotechnology measurements. The 124-page handbook provides practical information on making DC and pulsed measurements on nanomaterials and devices. It is divided into five sections covering challenges in making these measurements, measurement tips for carbon nanotubes, analysis of GaN materials, how to make low-current, low power measurements on nanoscale materials, and more.
