Atomic Scale Resoltion Imaging and Spectroscopy of 2-D and 2-D-3D Materials for Functional Applications
Abstract
2-D Materials have many superlative electronic and optical properties that can be tuned using doping or by combining them in assembled heterolayers, also known as Van der Waals heterostructures, in which each layer interacts electronically and optically but is bonded with weak Van der Waals forces. Synthesizing complex heterostructure stacks at scale usually requires control over the growth parameters of a laterally bulky, but vertically self-terminating process. In order to achieve reliable growth results, the details of the synthesis at each processing step and the atomic structure of the heterostructure must be examined at the atomic scale. In this study, we will use scanning transmission electron microscopy (STEM), electron energy loss spectroscopy (EELS), and energy dispersive spectroscopy (EDS), to relate the growth process to the material structure at each step of the heterostructure synthesis process.
