1. Graphene FETs in Microwave Applications
Sammanfattning : Graphene is a one-atom-thick sheet of carbon with numerous impressive properties. It is a promising material for future high-speed nanoelectronics due to its intrinsic superior carrier mobility and very high saturation velocity. LÄS MER
2. Microwave characterisation of electrodes and field effect transistors based on graphene
Sammanfattning : 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. LÄS MER
3. Microwave and millimeter-wave FETs and noise parameter measurements
Sammanfattning : .... LÄS MER
4. Microwave Transistor Noise Model Extraction Methods and a Non-Contacting Scattering Parameter Measurement Method
Sammanfattning : This thesis has two parts. The first part discuss noise model extraction methods for FETs. The second part describe theory and implementation of a non-contacting S-parameter measurement method. Noise is an important aspect for a circuit designer, because noise generated in the circuit is a sensitivity limiting factor. LÄS MER
5. Characterisation and Modelling of Graphene FETs for Terahertz Mixers and Detectors
Sammanfattning : Graphene is a two-dimensional sheet of carbon atoms with numerous envisaged applications owing to its exciting properties. In particular, ultrahigh-speed graphene field effect transistors (GFETs) are possible due to the unprecedented carrier velocities in ideal graphene. LÄS MER
