dc.description.abstract | In this dissertation, we describe experimental investigations of charge transport properties of both mechanically exfoliated and chemical vapor deposited (CVD) graphene and its potential applications using functional ferroelectric substrates. We demonstrated a non-volatile memory device in a graphene field-effect transistor structure using ferroelectric gating. Two distinct bistable resistance states were maintained by controlling the polarization of the ferroelectric thin film. Furthermore, this thesis is devoted a better understanding of CVD graphene. We elucidated a new type of quasi-periodic nanoripple arrays (NRAs) within a single graphene domain. The impact of these NRAs on charge transport of CVD graphene was also studied. Utilizing the hybrid CVD graphene and ferroelectric polymer structure, we demonstrated a novel type of flexible transparent conductors with low sheet resistance, high transparency and good mechanical flexibility. By transferring large-scale CVD graphene to wafer-size ferroelectric inorganic substrates (PZT), an array of low-voltage operation transistors and non-volatile memory devices were fabricated and investigated. | |
