Electronic properties and transport measurements of the hybrid bismuth/bismuthene heterostructure. (a) Electronic band structure of the bismuth/bismuthene hybrid, obtained by ab initio calculations. (b) Projected density of states for the hybrid material (black) and β-bismuth (red). Newly formed states around the Fermi energy are generated for the hybrid material. (c) SEM image of contacted individual crystallite for transport measurements. (d) I–V curves showing a linear behavior for different gate voltages ranging from −90 to +90 V for room temperature transport measurement.
