Description
2-dimensional materials have gained much popularity after the rise of graphene with its unique physical properties such as high electrical conductivity, high thermal conductivity, and high elasticity. There is an active search for 2D materials beyond graphene to improve performance in energy applications, sensors, and optoelectronic devices. Recently, transition metal dichalcogenides such as molybdenum disulfide (MoS2) are on the rise. However, MoS2 is well researched whereas molybdenum oxide (MoOx) has been studied less. Molybdenum oxide can be in various forms such as MoO, MoO2, and MoO3. MoO2 and MoO3 are the most stable, these films can be tuned for various properties. The focus of this study is to synthesize an ultra-thin film or 2D structure of MoO3 thin films on various substrates. The synthesis method is pulse laser deposition which allows fine-tune growth parameters to produce a thin film of MoO3. Through varying growth parameters including the deposition environment, energy density, and growth temperature. Characterizations include Raman Spectroscopy, X-ray Diffraction, electrical measurements, Scanning Electron Microscopy, Photoluminescence and more. This work aims to provide material solutions for applications in various industries.
