Photoluminescence (or PL) is a spectroscopy technique providing information on electrical and optical properties of semiconductor materials, such as bandgap, emission wavelength, crystallinity and crystal structure, defects etc…
A PL Mapper is a laser based instrument used to generate maps of several parameters over full wafers by measuring optical luminescence emission from materials excited with energy above their bandgap.
HORIBA Scientific micro-PL mapping systems are used to image small features made out of those semiconducting materials, such as diodes or nano structures like Gallium Nitride (GaN) or Silicon (Si) nanowires, Carbon Nanotubes etc…
Since the Photoluminescence Microscope systems are based on HORIBA Scientific leading Raman spectrometer systems, Raman studies can also be conducted on the same instrument.
Photoluminescence Mapping systems from HORIBA Scientific are used for research or production environments, and can be fitted with temperature controlled cells (LN2 or He cryostats) to measure photoluminescence emission at low temperature. This technique usually helps getting clearer information, from sharper spectral features.
