University of Texas, Dallas (01/2014 – 12/2015)


I worked as a research assistant at Wallace group for two years. I was very excited to be a part of the group, as it was just a few years after Geim and Novoselov won the Nobel Physics Prize in 2010 over the first ever mechaical exfoliation of monolayer graphene, and properties of graphene were being rapidly explored.

I had the opportunity to work on many exciting projects: growing graphene in CVD (chemical vapor deposition) chambers; transfering them onto various substrates for device applications; characterizing samples with Raman spectroscopy, in-situ XPS (X-ray photoelectron Spectroscopy), SEM (scanning electron microscopy), AFM (atomic force microscopy, STM (scanning tunneling microscopy), etc. I also worked on a few projects involving TMDs (transtion metal dichalcogenides) and black phosphorus, to study there surface structure and electrical properties.
