Probing Atomic Structure and Excitons in 2D Heterostructures Through Cryogenic STEM-EELS

Funding

Research supported by the U.S. Department of Energy (DOE), Office of Science, Office of Basic Energy Sciences Data, Artificial Intelligence, and Machine Learning at DOE Scientific User Facilities Program. Microscopy was performed as part of a user proposal at the Center for Nanophase Materials Sciences (CNMS), which is a US DOE Office of Science User Facility at Oak Ridge National Laboratory (ORNL). Microscopy performed using instrumentation within ORNL’s Materials Characterization Core provided by UT-Battelle, LLC, under Contract No. DE-AC05-00OR22725 with the DOE and sponsored by the Laboratory Directed Research and Development Program of ORNL. This manuscript has been authored by UT-Battelle, LLC, under Contract No. DE-AC0500OR22725 with the U.S. Department of Energy. The Department of Energy will provide public access to these results of federally sponsored research in accordance with the DOE Public Access Plan (http://energy.gov/downloads/doe-public-access-plan)
