Cryogenic magnetotransport study displaying correlated physics in thin HfTe₅

Van der Waals (vdW) topological materials provide a unique platform for studying the role dimensionality plays on topological properties. Topological pentatellurides exhibit a vdW layered structure, have been shown to display intriguing quantum transport properties in bulk samples. Here we report magnetotransport measurements of HfTe₅ thin flakes displaying correlated physics, ranging in thickness from 12nm to 280nm. The samples are prepared inside an inert argon-filled glovebox using a novel cryogenic dry-transfer technique and capped with hexagonal boron nitride (hBN) to ensure pristine sample quality. We present characterization through electron-transport under large magnetic fields and at temperatures ranging from room temperature to 10mK.
