Synthesis Methods and Defects
Research gap analysis derived from 2 physics papers in our local library.
The gap
The synthesis methods for two-dimensional materials and their defect states need further investigation. Specifically, large-scale wafer-scale protocols, semi-sealed CVD methods, and the use of EPR or XPS are underdeveloped.
Consensus across the literature
Papers collectively establish the need for improved synthesis methods but leave open how to minimize defects through specific techniques like EPR or XPS.
Research trend
Emerging — attention growing, methods still coalescing.
