  The study of two- dimensional (2D) materials is a rapidly growing area within
nanomaterial research. However, the high equipment costs, which include the
processing systems necessary for creating these materials, can be a barrier to
entry for some researchers interested in studying these novel materials. Such
process systems include those used for chemical vapor deposition. This article
presents the first open-source design for an automated chemical vapor
deposition system that can be built for less than a third of the cost for a
similar commercial system. Our design can be easily customized and expanded on,
depending upon the needs of the user. With a process chamber built as
described, we demonstrate that a variety of 2D nanomaterials and their
heterostructures can be grown via chemical vapor deposition. Specifically, our
experimental results demonstrate the capability of this open-source design in
producing high quality, 2D nanomaterials such as graphene and tungsten
disulfide, which are at the forefront of research in emerging semiconductor
devices, sensors, and energy storage applications.
