Correlating Atomic Structure with Individual Quantum Emitters
In a study published Advanced Materials, researchers demonstrated a novel approach to correlate the atomic-scale defects with individual quantum emitters hosted in hexagonal boron nitride (hBN).
(a) STEM-CL setup in QuEEN-M enabling (b) sub-10 nm CL mapping resolution. (c) HAADF image and (d) atomic structure of vertical carbon dimer for the 440 nm quantum emitter with (e) g2(0) = 0.3.
Scientific Achievement
Researchers demonstrated a novel approach to correlate the atomic-scale defects with individual quantum emitters hosted in hexagonal boron nitride (hBN).
Significance and Impact
This approach enabled the precise engineering and deterministic creation of quantum emitters, a foundational step toward scalable quantum technologies such as quantum communication and computing.
Research Details
- At CNM, the newly developed QuEEN-M was used for nanometer-resolution STEM-cathodoluminescence (STEM-CL), atomic-resolution STEM-EELS and HAADF imaging for the structure-optical property correlation.
- VASP, Carbon, FANTASTX, and Ingrained were used at CNM for structural modeling.
