To achieve better control over these properties for fundamental studies and various applications, there have been considerable efforts to manipulate the twist angle. Despite rigorous efforts to control the twist angle of stacked two-dimensional (2D) layers, there remains a challenge in perfectly aligning the crystalline orientation due to mechanical limitations and the inevitable formation of incommensurate regions. Here, we report a thermally activated atomic reconstruction of randomly stacked transition metal dichalcogenides (TMDs) multilayers into fully commensurate (FC) heterostructures with zero-twist-angle by encapsulation annealing, regardless of twist angles of as-stacked samples and large lattice mismatches. We also demonstrate the selective formation of R- and H-type FC phases with a seamless lateral junction using chemical-vapor-deposited TMDs. The resulting FC phases exhibit strong photoluminescence (PL) enhancement of the interlayer excitons even at room temperature due to their commensurate structure with aligned momentum coordinates. Our work not only shows a way to fabricate zero-twisted 2D bilayers with R and H-type configurations, but also provides a platform for studying their unexplored properties, such as interlayer excitons, interlayer valley, and interlayer ferroelectrics. description_type: abstract lang: en ## Creator - name: Ji-Hwan Baek role: author - name: Hyoung Gyun Kim role: author - name: Soo Yeon Lim role: author - name: Seong Chul Hong role: author - name: Yunyeong Chang role: author - name: Huije Ryu role: author - name: Yeonjoon Jung role: author - name: Hajung Jang role: author - name: Jungcheol Kim role: author - name: Yichao Zhang 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: Pinshane Y.
