Faraday´s Induction Experiment in Nano-Transformers

Faraday´s induction experiment in a nanometer scale was performed. Various nano-transformers with the smallest coupling area of approximately 1 mum² were fabricated, and the induced open circuit voltages were measured. The output responses showed linear dependences on both the magnitude and the frequency of the input current. This suggested that the nano-transformer behaved as a linear transformer. The extracted mutual inductance value was approximately 30 nH and it was several orders larger than the one expected from 1 mum² coupling area.
