Abstract

Molybdenum disulfide is a Transition metal dichalcogenide (TMD) material that has received much attention due to its semiconducting properties in the direct band-gap at the single layer limit and indirect band-gap in the bulk form. During our novel High-Vacuum deposition growth process of thin film MoS2, a CCD camera can be used to control and monitor the growth in-situ by using a custom Labview software. Over the period of the growth it was observed that there was a change in the wavelength of the light in the visible spectrum reflected from the surface of the sample. By using the data from the growth and the Raman spectroscopy of the samples it was concluded that there was a correlation between the change in the wavelength of the light to the number of layers of MoS2 present on the substrate. My research was mainly focused on preparing a software in labview that can adjust the parameters of the camera in relation to the variables inside the growth chamber in order to monitor the growth process accurately.
