Evaluation of a Luminescent Semiconductor on the Nanometer Scale
August 23, 2022
Introduction
Photoluminescence (PL) and electroluminescence (EL) measurements are standard techniques for evaluation of the crystallinity, functionality and luminescent mechanism of semiconductors. For these samples, near-field optical microscopy is the only effective method for characterization of the composition and distribution of luminescent centers on the nanometer scale.
In combination with a superconductive magnetic field, luminescent spectral measurements of the sample surface can be accomplished with nano-scale spatial resolution while applying temperatures as low as 7K and magnetic fields as high as 4 Tesla.
