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. text/plain application/gzip text/markdown https://doi.org/10.24435/materialscloud:gq-6x oai:materialscloud.org:2364 mcid:2025.4 eng Materials Cloud https://doi.org/10.1038/s41699-024-00449-w https://archive.materialscloud.org/communities/mcarchive https://doi.org/10.24435/materialscloud:qq-aq info:eu-repo/semantics/openAccess Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode Twisted multilayer graphene Tight-binding WannierTools 2D materials Experimental MARVEL Electric field tunable bandgap in twisted double trilayer graphene info:eu-repo/semantics/other
