Proximity induced band gap opening in topological-magnetic heterostructure (Ni₈₀Fe₂₀/p-TlBiSe₂/p-Si) under ambient condition.

ABSTRACT: The broken time reversal symmetry states may result in the opening of a band gap in TlBiSe₂ leading to several interesting phenomena which are potentially relevant for spintronic applications. In this work, the quantum interference and magnetic proximity effects have been studied in Ni₈₀Fe₂₀/p-TlBiSe₂/p-Si (Magnetic/TI) heterostructure using physical vapor deposition technique. Raman analysis shows the symmetry breaking with the appearance of A²_1u mode. The electrical characteristics are investigated under dark and illumination conditions in the absence as well as in the presence of a magnetic field. The outcomes of the examined device reveal excellent photo response in both forward and reverse bias regions. Interestingly, u
