High resolution STEM study of dy-doped Bi2Te3 thin films

Abstract:
Breaking the time-reversal symmetry (TRS) in three-dimensional (3D) topological insulators (TIs) is essential for unlocking exotic physical states and exploring potential device application. Doping of the prototypical 3D-TI Bi2Te3 with transition metal ions can lead to ferromagnetic ordering at low temperatures. Here we report the study of incorporation of dysprosium (Dy) into Bi2Te3 with the intent to achieve higher ferromagnetic ordering temperatures and higher magnetic moments.
