[Th-P-10] Coulomb Correlations in the Shift and Ballistic Photogalvanic Effect in TMDC Monolayers

〇Grigory Budkin¹, Eougenious Ivchenko¹ (1. Ioffe Institute (Russia))

A microscopic theory of the photogalvanic effect in transition metal dichalcogenide monolayers is developed, including Coulomb correlations. It is demonstrated that while the shift contribution is exciton-enhanced, the ballistic contribution, arising from Coulomb scattering, dominates in realistic structures.
