Since the initial discovery of correlated phases in twisted bilayer graphene, a wide range of moiré materials have emerged with fascinating electronic properties. While the field of twistronics has rapidly evolved and now includes a range of multi-layered systems, moiré systems comprised of double trilayer graphene remain elusive. Here, we report electrical transport measurements combined with tight-binding calculations in twisted double trilayer graphene (TDTLG). We demonstrate that small-angle TDTLG (~1.7−2.0ᵒ) exhibits an intrinsic bandgap at the charge neutrality point. Moreover, by tuning the displacement field, we observe a continuous insulator-semimetal-insulator transition at the CNP, which is also captured by tight-binding calculations. These results establish TDTLG systems as a highly tunable platform for further exploration of magneto-transport and optoelectronic properties.</dc:description> <dc:identifier>https://archive.materialscloud.org/record/2025.4</dc:identifier> <dc:identifier>doi:10.24435/materialscloud:gq-6x</dc:identifier> <dc:identifier>mcid:2025.4</dc:identifier> <dc:identifier>oai:materialscloud.org:2364</dc:identifier> <dc:language>en</dc:language> <dc:publisher>Materials Cloud</dc:publisher> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode</dc:rights> <dc:subject>Twisted multilayer graphene</dc:subject> <dc:subject>Tight-binding</dc:subject> <dc:subject>WannierTools</dc:subject> <dc:subject>2D materials</dc:subject> <dc:subject>Experimental</dc:subject> <dc:subject>MARVEL</dc:subject> <dc:title>Electric field tunable bandgap in twisted double trilayer graphene</dc:title> <dc:type>Dataset</dc:type> </oai_dc:dc>
