Our paper describing new results related to the two-dimensional material heterobilayer system of MoSe2/WSe2 has been published in Nature communications, read it here.
We have found two types of localized exciton emissions in this heterobilayer system, where we attribute one of them to defect-localized excitons and the other one to moiré-localized excitons. Moreover, at strong excitation and elevated temperatures we observe emission originating from biexcitons – for the first time.
Congrats to this exciting work, mainly to Hanlin, who was the major driving force behind the project! A wonderful collaboration with the groups of Ermin Malic, Sanshui Xiao, Zhipei Sun, and Saroj Dash!
