a Schematic of the sample preparation process for measuring electrical transport. Patterned Ti (10 nm)/Au (50 nm) electrodes were deposited on Si/SiO2 substrates. A freshly exfoliated Ta2Se single crystal with a clean surface was attached to 3 M tape and then transferred onto the designated patterned electrode. b–d T-dependent ρ, nh, and μH properties of single-crystalline Ta2Se.
