Study and tune quantum effects using cathodoluminescence

Perform cathodoluminescence (CL) imaging to study and tune the optical properties of quantum materials, including quantum-confined structures, 2D materials, and nanoscale emitters. Additionally, CL can be used to investigate fundamental light-matter interactions, such as the coupling between photons and fast electrons in the near-field of photonic nanostructures.

2D Materials

Reveal the local optical properties of 2D materials

Use CL to analyze the local optical properties of 2D materials, including wide-bandgap materials such as hexagonal boron nitride (hBN), transition metal dichalcogenides (TMDCs) such as WSe2, and multilayered devices. Encapsulate TMDCs in hBN to enhance emission efficiency, protect the layer from damage, and increase the interaction with the electron beam.
