Here, we reveal that a multilayer MoS2-based tunnel junction exhibits substantial negative differential resistance (NDR) owing to the presence of a minigap, which is the energy gap between the upper and lower bands of the valence band at the \U0010FC00 point. We fabricated a highly p-doped multilayer p+-MoS2/h-BN/p+-MoS2 tunnel junction. When a bias is applied across the junction, holes at the Fermi level at the \U0010FC00 point in the valence band of the source-side p+-MoS2 resonantly tunnel to the drain-side p+-MoS2 with momentum conservation. When the energy of the injected hole coincides with the minigap of the drain-side p+-MoS2, the tunneling conductance is suppressed; thus, NDR is observed in the current-voltage characteristics. We identified minigap-induced NDR over a broad range of MoS2 thicknesses, including the bulk, that was observable even at room temperature." description_type: abstract lang: und ## Creator - name: Seiya Kawasaki role: author - name: Kei Kinoshita role: author orcid: https://orcid.org/0009-0005-4586-734X - name: Rai Moriya role: author orcid: https://orcid.org/0000-0001-7471-7432 - name: Momoko Onodera role: author orcid: https://orcid.org/0000-0001-9457-6796 - name: Yijin Zhang role: author orcid: https://orcid.org/0000-0003-1127-1124 - name: Kenji Watanabe role: author orcid: https://orcid.org/0000-0003-3701-8119 - name: Takashi Taniguchi role: author orcid: https://orcid.org/0000-0002-1467-3105 - name: Takao Sasagawa role: author orcid: https://orcid.org/0000-0003-0149-6696 - name: Tomoki Machida role: author orcid: https://orcid.org/0000-0002-1938-7415 ## Contact agent ## Publisher organization: American Physical Society (APS) ## Managing organization ## Keyword - subject: Negative differential resistance schema: not_defined - subject: MoS2 schema: not_defined - subject: tunnel junction schema: not_defined ## Rights - identifier: https://creativecommons.org/licenses/by/4.0/ ## Other identifier(s) ## Data origin ## Embargo ## Journal - title: Physical Review Research issn: '26431564' volume: '6' issue: '3' article_number: '033011' ## Conference ## Related item ## Funding - identifier: JPMJCR15F3 funder_name: Japan Science and Technology Corporation - identifier: JPMJCR20B4 funder_name: Japan Science and Technology Corporation - identifier: JPMJMI21G9 funder_name: Japan Science and Technology Corporation - identifier: JPMJPR20L5 funder_name: Japan Science and Technology Corporation - identifier: JP20H00127 funder_name: Japan Society for the Promotion of Science - identifier: JP20H00354 funder_name: Japan Society for the Promotion of Science - identifier: JP21H04652 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: JP21H05236 funder_name: Japan Society for the Promotion of Science - identifier: JP21K18181 funder_name: Japan Society for the Promotion of Science - identifier: JP22H01898 funder_name: Japan Society for the Promotion of Science - identifier: JP22K18317 funder_name: Japan Society for the Promotion of Science - identifier: JP22K14559 funder_name: Japan Society for the Promotion of Science - identifier: JP22J22105 funder_name: Japan Society for the Promotion of Science - identifier: JP22KJ1104 funder_name: Japan Society for the Promotion of Science - identifier: JP23H02052 funder_name: Japan Society for the Promotion of Science - funder_name: Inoue Foundation for Science - funder_name: Tokuyama Science Foundation - funder_name: Support Center for Advanced Telecommunications Technology Research 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: d911de95-c8bf-4146-a545-c6a52be8aaba filename: PhysRevResearch.6.033011.pdf content_type: application/pdf size: 3455778 md5: 3ab17da4c2be523cb8d9b9c81dbcbccd ## Thumbnail fileset_id: d911de95-c8bf-4146-a545-c6a52be8aaba filename: PhysRevResearch.6.033011.pdf
