We have combined sorting and assembling techniques to fabricate devices from single-walled carbon nanotubes (CNTs) with well defined properties [1]. On such devices we have recently performed a range of experiments. I will report on hydrogen sensing with chirality-sorted CNTs [2], electroluminescence from metallic CNTs [3], and CNTs as molecular leads for molecular electronics [4]. I will also present voltage-contrast scanning electron microscopy as a tool for rapid device screening [5].
