Abstract

Carbon nanotube (CNT) forests are the darkest man-made materials on Earth. The optical properties of CNT forests have been found to be dependent on their density and height. We aim to fabricate CNT forests with periodic patterns in height and study their reflectivity, particularly in the mid-infrared range. The height variation will be achieved by photolithography on quartz wafers followed by CNT growth.


Our second objective is to pattern CNT forests into arrays of cylinders which could be used as chemical sensors. Different spacings of CNTs and diameters of the cylinders will be tested to see if metal nano-clusters can be distributed evenly along the vertical dimension of the cylinders.
