DOI: 10.1021/acs.nanolett.8b02816
Abstract: Hexagonal Si allotropes are expected to enhance light absorption in the visible range as compared to common cubic Si with diamond structure. Therefore, synthesis of these materials is crucial for the development of Si-based optoelectronics.… read more here.
