Unveiling the Spin-Valley Structure of Dipolar Exciton Ladders in R-stacked WSe${}_2$/WS${}_2$ Moiré Heterobilayers

Byeong Wook Cho, Tatyana V. Ivanova, Zhe Li +4

Localized interlayer excitons in moiré heterobilayers can form dipolar exciton ladders, yet their internal spin-valley structure remains unresolved. Here, we use helicity-resolved…
