Superconductivity and vortex structure on Bi${}_2$Te${}_3$/FeTe${}_{0.55}$Se${}_{0.45}$ heterostructures with different thickness of Bi${}_2$Te${}_3$ films

Kailun Chen, Mingyang Chen, Chuanhao Wen +3

Using scanning tunnel microscopy (STM), we investigate the superconductivity and vortex properties in topological insulator Bi${}_2$Te${}_3$ thin films grown on the iron-based supe…
