Twisted Graphene Heterostructures*

Twisted graphene heterostructures have been found to display unique properties in the past such as with the case of a 1.1 degree twist resulting in superconductivity. Theory has suggested that there is another angle that its properties should change dramatically at approximately a 12 degree twist. This project regards a heterostructure with a twist of 14 degrees in order to provide experimental data for twist angles near the angle where the property changes are maximized. Analysis was performed through Raman Spectrometry and results matched expectations with an increase in the phonon band associated with sp2 orbital resonance.
