Dennice Roberts is a postdoctoral researcher at NREL focused on synthesis and characterization of materials for renewable energy applications using low-cost and materials-by-design methods. Her work spans multiple research areas and is currently focused on: 1) development of low-cost growth methods for high efficiency III-V tandem solar cells, and 2) design and synthesis of metastable chalcogenide heterostructures for neuromorphic computing.
She is specifically interested in kinetic trapping of novel structures and the the effects of surfaces and interfaces on the properties of energy-related material systems. Her synthesis experience includes nanoparticle growth, vacuum deposition, and hydride vapor phase epitaxy. She has characterization experience encompassing a variety of structural, optical, and electrical methods with particular expertise in X-ray diffraction techniques.
