Abstract
Provided herein are wafers that can be used to align carbon nanotubes, as well as methods of making and using the same. Such wafers include alignment areas that have four sides and a surface charge, where the alignment areas are surrounded by areas that have a surface charge of a different polarity. Methods of the disclosure may include depositing and selectively etching a number of hardmasks on a substrate. The described methods may also include depositing a carbon nanotube on such a wafer.
