WebOct 7, 2024 · Figure 1A shows that the interlayer exciton emission has a peak wavelength at ~784 nm, which agrees with K-Q (K′-Q′) transitions. The fixed orientation of the exciton dipole direction also agrees with experiment demonstrated below. The wavelength does not overlap with the intralayer exciton emission (~736 nm) ( 6, 30 ). WebApr 13, 2024 · Due to the unique layered structure of these materials, charge transport across the vdW gaps via tunneling is governed by individual valleys with different interlayer coupling strengths. On the other hand, the omnipresent point defects in TMDCs could possibly cause intervalley scattering between these valleys.
WebFeb 12, 2016 · Because of the large momentum difference, interlayer hopping between + KW and − KM valleys is strongly suppressed. Conversely, the + KW and + KM valleys have small momentum mismatch, and the spin-conserving interlayer hopping between these valleys becomes the dominant relaxation channel.
