The UV-visible spectrometer is used to determine the thickness and the bandgap of semiconductor layers grown by the MOCVD system.
Light Microscope
The optical microscope in this lab is used to investigate the initial surface property of the layers, for example pits, scratches, and any feature on the substrate and the layers.
Oceanoptics Spectrometer
The miniature spectrometer is built by Ocean Optics (Ocean Insight 2000+). It is used to measure the optical spectrum from light emitting diode structures when energized by the probe station. It can design and build photonics systems for material inspection and chemical identification. It covers a range of 200 to 1,100 nm with 0.1 nm resolution.
