Without the graphene capping layer, a squeezing process with an AFM tip induces applied-force-dependent charges of \u0394n \u223c 2 \u00d7 10^12 cm^\u20132 \u03bcN^\u20131, resulting in the significant intensity of trions in photoluminescence spectra of MoSe2 at low temperature. We found that a hBN/MoSe2/hBN prepared with the \u201cgraphene-capping-assisted AFM nano-squeezing method\u201d shows a strong excitonic emission with negligible trion peak, and the residual line width of the exciton peak is only 2.2 meV, which is comparable to the homogeneous limit. Furthermore, in this high-quality sample, we found that the formation of biexciton occurs even at extremely low excitation power (\u03a6ph \u223c 2.3 \u00d7 10^19 cm^\u20132 s^\u20131) due to the enhanced collisions between excitons.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "ACS Publications", "subitem_publisher_language": "en"}]}, "item_9_relation_43": {"attribute_name": "\u95a2\u9023\u60c5\u5831", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1021/acsnano.0c08642", "subitem_relation_type_select": "DOI"}}]}, "item_9_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "This document is the Accepted Manuscript version of a Published Work that appeared in final form in [ACS Nano], copyright \u00a9 American Chemical Society after peer review and technical editing by the publisher.
