The Search for Quantum Light Sources in 2D Sb₂O₃

In the design of photonic quantum computers, sources of quantum light are among the most basic building blocks. These sources are known as Single Photon Emitters (SPEs), which emit a single photon per excitation cycle. In recent years, defects in 2D material systems such as Hexagonal Boron-Nitride (hBN) and Transition Metal Dichalcogenides (TMDCs) have proved to be promising platforms for realizing scalable solid-state quantum light sources. However, other 2D material systems remain relatively unexplored. The exfoliation, transfer, and photoluminescence (PL) spectroscopy of 2D Antimony Trioxide(Sb₂O₃) was performed in this work. Transfer proved to be difficult, and no monolayer or quantum emitters were found. A broad defect band in the PL spectrum requires further investigation at cryogenic temperatures. Further defect and strain engineerings such as plasma irradiation or nano-pillars could be promising paths.
