Graphene Layering in Coke Deposit on LTC Contacts
This image shows the crystal structure density and orientation of graphene in the coke deposit on a Load Tap Changer (LTC) contact. The intensity of the blue or yellow shows the degree of crystallinity while the blue indicates that the omega refractive index is oriented NE-SW and yellow indicates the omega refractive index is oriented NW-SE.
