    Activity: Talk or presentationOral presentation


    A set of ring-shaped test structures is presented for electrical characterization of 2D as-deposited layers on Si that electrically interact with the substrate. The test method is illustrated by investigation of 3 different nm-thin layers that are expected to form an interfacial layer of negative fixed charge. A test procedure is described that gives a low turnaround time and non-destructive way of evaluating different deposition methods in terms of diode characteristics, interface conductance, and electron carrier injection into the deposited layer.
