Charge movement in a mixed-dimensionality hetero-trilayer material: Photoexcited electrons and holes travel from the transition metal dichalcogenide layer (top) through single-walled carbon nanotubes (middle), resulting in a long charge recombination lifetime of 1.2 microseconds, which has potential applications in optoelectronics and energy harvesting. Image by Alexis Myers, NREL
Successfully innovating optoelectronic semiconductor devices depends a lot on moving charges and excitons—electron-hole pairs—in specified directions for the purpose of creating fuels or electricity.
In photosynthesis, pigment molecules absorb and transfer solar energy to a reaction center, where the energy is converted and used...
