However, such twisted multilayers are often prepared using mechanically- exfoliated monolayer flakes with unintended shapes through a time-consuming search for such materials. Here, we report the rapid and all-dry fabrication of twisted multilayers using chemical vapor deposition (CVD) grown transition metal chalcogenide (TMDC) monolayers. The present dry transfer process demonstrates the one-step fabrication of more than 100 twisted bilayers and the sequential stacking of a twisted 10-layer MoS2 single crystal. Furthermore, we also fabricated the hBN-encapsulated TMDC monolayers and various twisted bilayers including MoSe2/MoS2, MoSe2/WSe2, and MoSe2/WS2. The interlayer interaction and quality of dry-transferred, CVD-grown TMDCs were characterized by using photoluminescence (PL), cathodoluminescence (CL) spectroscopy, and cross sectional electron microscopy. The prominent PL peaks of interlayer excitons can be observed for the MoSe2/MoS2 and MoSe2/WSe2 with small twist angles at room temperature. We also found that the optical spectra were locally modualted due to the nanosized bubbles, which are formed by the presence of interface carbon impurities. The present findings provide a widely applicable potential of the present method and enable an efficient search of the emergent optical and electrical properties of TMDC-based vdW heterostructures. description_type: abstract lang: und ## Creator - name: Hibiki Naito role: author - name: Yasuyuki Makino role: author - name: Wenjin Zhang role: author - name: Tomoya Ogawa role: author - name: Takahiko Endo role: author - name: Takumi Sannomiya role: author - name: Masahiko Kaneda role: author - name: Kazuki Hashimoto role: author - name: Hong En Lim role: author - name: Yusuke Nakanishi role: author - name: Kenji Watanabe role: author orcid: https://orcid.org/0000-0003-3701-8119 organization: National Institute for Materials Science - name: Takashi Taniguchi role: author orcid: https://orcid.org/0000-0002-1467-3105 organization: National Institute for Materials Science - name: Kazunari Matsuda role: author - name: Yasumitsu Miyata role: author ## Contact agent ## Publisher organization: Royal Society of Chemistry (RSC) ## Managing organization ## Keyword - subject: van der Waals layered materials schema: not_defined - subject: chemical vapor deposition schema: not_defined - subject: twisted multilayers schema: not_defined ## Rights - identifier: cc-by-3.0 ## Other identifier(s) ## Data origin ## Embargo ## Journal - title: Nanoscale Advances issn: '25160230' volume: '5' issue: '18' start_page: 5115 end_page: 5121 ## Conference ## Related item ## Funding - identifier: JPMJFR213J funder_name: Japan Science and Technology Agency - identifier: JPMJFR213X funder_name: Japan Science and Technology Agency - identifier: JP19K22142 funder_name: Japan Society for the Promotion of Science - identifier: JP20H00354 funder_name: Japan Society for the Promotion of Science - identifier: JP20H05664 funder_name: Japan Society for the Promotion of Science - identifier: JP21H05232 funder_name: Japan Society for the Promotion of Science - identifier: JP21H05233 funder_name: Japan Society for the Promotion of Science - identifier: JP21H05234 funder_name: Japan Society for the Promotion of Science - identifier: JP21H05235 funder_name: Japan Society for the Promotion of Science - identifier: JP22H00280 funder_name: Japan Society for the Promotion of Science - identifier: JP22H00283 funder_name: Japan Society for the Promotion of Science - identifier: JP22H04957 funder_name: Japan Society for the Promotion of Science - identifier: JP22K18986 funder_name: Japan Society for the Promotion of Science - identifier: JP22KJ2561 funder_name: Japan Society for the Promotion of Science - identifier: JP23H02052 funder_name: Japan Society for the Promotion of Science - identifier: JP23K13635 funder_name: Japan Society for the Promotion of Science - identifier: JP23K04530 funder_name: Japan Society for the Promotion of Science - identifier: ZE2023B-05 funder_name: Kyoto University - funder_name: Murata Science Foundation ## Instrument ## Instrument operator ## Instrument managing organization ## Measurement method ## Specimen ## Chemical composition ## Structure for specimen ## Structural feature for specimen ## Specific property for specimen ## Process for specimen treatment ## Computational method ## Energy level/transition state ## Software ## Custom property ## Fileset - id: fa5133d4-af97-45e2-aa83-d9b67e4b780b filename: d3na00371j.pdf content_type: application/pdf size: 864927 md5: f2d8f2c5b9900dfadae4d744200e5c5a ## Thumbnail fileset_id: fa5133d4-af97-45e2-aa83-d9b67e4b780b filename: d3na00371j.pdf
