Join application scientists Dr Jining Xie and Dr Song Xu of Agilent Technologies for a unique scientific webinar in May detailing brand new techniques for exploring the properties of graphene at the nanoscale!
First, imaging of graphene on different substrates via low-voltage field emission scanning electron microscopy will be demonstrated. Various FE-SEM imaging modes are utilized to study surface morphology at a broad range of magnifications; tuning the beam voltage (down to 500 V) controls charging problems caused by the insulating substrates.

Next, the use of 'frequency modulation electrostatic force' will be described. This FM-KFM technique reveals electrical potential variation generated by the contact interface between the graphene and substrate. Combining signal contrast from multiple channels, AFM’s ability to study/identify graphene without optical methods will be demonstrated.
