Applications

THIN FILMS OF GaP

Spectral dependence of the Faraday MO effect with temperature dependence measurements were performed on a semiconductor 2 µm epilayer (GaP) grown with embedded metallic ferromagnetic nanoclusters (MnP).

PHOTOVOLTAIC

IMA™ provides spectrally and spatially resolved images. It was successfully used to investigate spatial distribution of opto-electronic properties of CIS, CIGS, GaAs and perovskite solar cells.

SWNT BREATHING MODES

Two narrowband tunable filters for resonance Raman spectroscopy (RRS) were designed to study the radial breathing modes of carbon nanotubes.
