Synthesis of Hexagonal Boron Nitride Thin Films

Mentor: Sefaattin Tongay
FURI: Spring 2019

Hexagonal boron nitride (hBN) is a wide band gap semiconductor with graphene-like structure and characteristics. This material has been identified as a potential candidate for diverse electronic, optoelectronic, nanophotonic and other applications. The goal of this project is to develop a method for synthesizing large domain, single crystalline hBN thin films through precipitation from an iron-chromium alloy solution. Bulk hBN was successfully grown using flux method and crystal identity and quality was confirmed by Raman spectroscopy, and X-ray diffraction. New methods for large scale hBN thin film growth with improved purity, optimized grain size and controlled thickness will be explored.

Catalytically Active Tungsten Diselenide (WSe2) for Artificial Photosynthesis

Mentor: Sefaattin Tongay
FURI: Fall 2018

Hydrogen Energy has great potential as a renewable form of energy for a sustainable future. The objective of this project is to introduce Niobium and Rhenium doping elements to monolayer Tungsten Diselenide to enhance the catalytic activity toward hydrogen generation in the process of photo-electrocatalysis. With control over defects, the number of active sites on the material surface is increased leading to higher rates of redox reactions at both electrodes of the photocatalytic cell. Future work includes analyzing the effect of Platinum, Palladium and Ruthenium as catalytically active point defects on the efficiency of hydrogen generation.
