Fig. 4: Correlation between the spin transport 1/e decay distances \({d}_{1/e}^{{{{\rm{s}}}}}\) and the LE-IX transport 1/e decay distances d1/e.
From: Long-distance decay-less spin transport in indirect excitons in a van der Waals heterostructure
The values for \({d}_{1/e}^{{{{\rm{s}}}}}\) and d1/e are taken from Fig. 2 and Supplementary Fig. S7. The data with the fit indicating diverging \({d}_{1/e}^{{{{\rm{s}}}}}\) and d1/e are presented by circles on the edge. The error bars represent the uncertainty in least-squares fitting the transport decays to exponential decays. The enhancement of \({d}_{1/e}^{{{{\rm{s}}}}}\) with d1/e is observed in a broad range of both excitation density and temperature variations, corresponding to the range of these parameters in Fig. 2 and Supplementary Fig. S7.
