Self-Driven and High-Performance Photodetector Based on Topological Insulator BiSb/Si Heterojunction for Visible Light Communication
A self-driven and high-performance photodetector based on BiSb/silicon heterostructure is firstly demonstrated, especially achieving excellent detectivity of 1.81 × 10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">14</sup> Jones, which is due to the high electron mobility and low dark current of BiSb. © 2025 The Author(s)
