Time-resolved cathodoluminescence imaging

Use time-resolved CL to unlock the decay trace and lifetime of your photon emitter. Additionally, you can conduct a comprehensive analysis of the photon distribution over time to gain detailed insights into your semiconductor or quantum material.

C_Text-and-image_Emitter-lifetime

Extract your photon emitter lifetime

Enable decay trace imaging on your SPARC system by adding the LAB Cube detector module, performing time-correlated single-photon counting and g(2) imaging. Acquire the decay trace and extract the lifetime of your photon emitter. This can be used to gain deeper insights into materials such as semiconductor material for optoelectronic devices, rare earth-doped material for scintillators, and nanomaterials.

C_Text-and-image_Photon-distribution

Observe the photon distribution over time

Gain insights into photon distribution over time by performing g(2) imaging using the LAB Cube module and a pulsed electron beam inside your SEM. Observe coherent CL, antibunching for quantum emitters, or bunching for incoherent emitters. 

C_Text-and-image_Pump-probe

Pump-probe spectroscopy

Extract dynamic information by performing pump-probe spectroscopy, in which ultrafast electron pulses are overlapped with ultrafast laser pulses on a sample. Enquire with the Delmic team about the possibilities.
