Local distribution of deep centers in GaP studied by infrared cathodoluminescence

GaAs/AlGaAs heterostructure nanowires studied by cathodoluminescence

In this report we explore the structural and optical properties of GaAs/AlGaAs heterostructure nanowires grown by metalorganic vapour phase epitaxy using gold seed-particles. The optical studies were done by low-temperature cathodoluminescence (CL) in a scanning electron microscope (SEM).We perform a systematic investigation of how thenanowire growth-temperature affects the total photon emissio...

Silicon-vacancy color centers in nanodiamonds: cathodoluminescence imaging markers in the near infrared.

We recently demonstrated [ 18 ] multi-color cathodoluminescence (CL) of nanodiamonds as a powerful tool for nanoscale imaging of biological structures. CL is the emission of light by matter as the result of electron bombardment. CL imaging of bulk matter is typically carried out in an electron microscope outfi tted with an optical detector, and is widely used in materials characterization. [ 19...
