The thin films of interest are grown using magnetron sputtering at the eMagic Lab. In particular, Au will be deposited on a 10mm x 10mm x 0.5mm MgO(001) substrate. Thickness measurements are important in characterizing the sample, and it is helpful to get an estimate of the thickness which serves as a reference when fitting data from spectroscopic ellipsometry(...")

We use a light bulb as the light source and grating to vary the wavelength of the light source. We will build a passive quenching configuration to get photons detected. Thus, by knowing which light source is working for the LEDs to detect photons, we can determine band gaps of each LEDs.")
