6. Design and Characterization of RF-Power LDMOS Transistors
Sammanfattning : In mobile communication new applications like wireless internet and mobile video have increased the demand of data-rates. Therefore, new more wideband systems are being implemented. LÄS MER
7. Vertical III-V Nanowire Tunnel Field-Effect Transistor
Sammanfattning : In this thesis fabrication and optimization of vertical III-V Tunneling Field-Effect transistors was explored. Usage of vertical nanowires, allows for combination of materials with large lattice mismatch in the same nanowire structure. LÄS MER
8. Wide Bandgap Semiconductor (SiC & GaN) Power Amplifiers in Different Classes
Sammanfattning : SiC MESFETs and GaN HEMTs have an enormous potential in high-power amplifiers at microwave frequencies due to their wide bandgap features of high electric breakdown field strength, high electron saturation velocity and high operating temperature. The high power density combined with the comparably high impedance attainable by these devices also offers new possibilities for wideband power microwave systems. LÄS MER
9. Design, Fabrication and Characterization of GaN HEMTs for Power Switching Applications
Sammanfattning : The unique properties of the III-nitride heterostructure, consisting of gallium nitride (GaN), aluminium nitride (AlN) and their ternary compounds (e.g. AlGaN, InAlN), allow for the fabrication of high electron mobility transistors (HEMTs). LÄS MER
