Can mechanical energy change
WebFeb 11, 2024 · This continuous strain change across the deformed structure induces a bandgap energy gradient, and therefore, provides efficient transport paths for photoexcited excitons in the deformed 2D lattice. We further demonstrated dynamic photoresponsivity modulation by structural modulation of a deformed 2D material, implying exciton drift … WebIn view of high ground stress, high geothermal temperature, and thermal hazard during deep mineral resource exploitation, the concept of phase-change heat storage backfill was put forward in this study. Further, the corresponding technical system was constructed and the main content involved in technical system, which is the optimized proportion of the …
