   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Agnimitra Saha; [2023]
   Keywords : Silicon Carbide; Gate Bias Stress; Threshold Voltage; On-state Resistance; Temperature; kiselkarbid; gate spännings-stress; tröskelspänning; on-resistansen; temperatur;

   Abstract : Silicon Carbide, a wide band gap (WBG) semiconductor, has pushed electrical limits beyond Silicon (Si) when it comes to power electronics. It has offered the electrification of society showing promise for a greener future. READ MORE

3. 2. Digital Front End Algorithms for Sub-Band Full Duplex

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Keywords : Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

   Abstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

4. 3. Radiation Effects on GaN-based HEMTs for RF and Power Electronic Applications

   University essay from KTH/Tillämpad fysik

   Author : Wilhelm Holmberg; [2023]
   Keywords : High Electron Mobility Transistor; HEMT; Gallium Nitride; GaN; Silicon Carbide; SiC; Proton Radiation; Galliumnitrid; GaN; Kiselkarbid; SiC; Kisel; Si; HEMT; Transistor; Protonstrålning;

   Abstract : GaN-HEMTs (Gallium Nitride-based High Electron Mobility Transistors) have, thanks to the large band gap of GaN, electrical properties that are suitable for applications of high electrical voltages, high currents, and fast switching. The large band gap also gives GaN-HEMTs a high resistance to radiation. READ MORE

5. 4. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines
