Fig. 3: Carrier dynamics of the 2D/3D HP interface.

a Staged TA kinetics probed at the characteristic wavelengths of dissimilar phases (520 nm for n = 1, 569 nm for n = 2, 614 nm for n = 3, 644 nm for n = 4, 760 nm for n = ∞). b Transient PL kinetics of the n = 2~4 2D phases and the n = ∞ 3D phase. c The dependence of the feature time of ① on the built-in potential of the 2D/3D HP interface. d–f Schematic illustrations of the carrier dynamics of ①, ②, and ③.
