1. Integration of graphene into MEMS and NEMS for sensing applications
University dissertation from KTH Royal Institute of TechnologyAbstract : This thesis presents a novel approach to integrate chemical vapor deposition (CVD) graphene into silicon micro- and nanoelectromechanical systems (MEMS/NEMS) to fabricate different graphene based MEMS/NEMS structures and explore mechanical properties of graphene as well as their applications such as acceleration sensing, humidity sensing and CO2 sensing. The thesis also presents a novel method of characterization of CVD graphene grain boundary based defects. READ MORE

2. Graphene Hot-electron Transistors
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : Graphene base transistors (GBTs) have been, recently, proposed to overcome the intrinsic limitations of the graphene field effect transistors (GFETs) and exploit the graphene unique properties in high frequency (HF) applications. These devices utilize single layer graphene as the base material in the vertical hot-electron transistors. READ MORE

3. Microwave characterisation of electrodes and field effect transistors based on graphene
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : The isolation of the two-dimensional material graphene, a single hexagonal sheet of carbon atoms, is believed to trigger a revolution in electronics. Theory predicts unprecedented carrier velocities in ideal graphene, from which ultrahigh speed graphene field effect transistors (GFETs) are envisioned. READ MORE

4. Plasmons in Nanostructured Graphene
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : Plasmons, collective electron density oscillations, provide physicists with intriguing challenges and possibilities. The inherent many-body properties of the plasmons together with their ability to localize light into small volumes make the plasmons interesting from both a purely theoretical viewpoint and an applications point of view.

5. Solution-Processable Conductive Graphene-Based Materials for Flexible Electronics
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : This thesis work explores electrical conductors based on few-layer graphene flakes as an enabler for low-cost, mechanically flexible, and high-conductivity conductors in large area flexible and printed electronic devices. The flakes are deposited from aqueous solutions and processed at low temperature. READ MORE
