| Description | The project was key platform in establishing research and industry based RF GaN on Si, this includes both passive and active on chip devices for MMIC applications. High performance RF HEMTs been realised and high Q passoves on GaN on Si substrates. The developed work is published at several IEEE journals and presented at international conferences. |
| Exploitation Route | The outcomes of this funding been taken forward via many ways, including commercial RF GaN technology based chip set technology development in collaboration with Compound Semiconductor Centre Ltd (CSC) and research at cardiff University, other Universities partners, PhD research projects and University used developing new practicle based teaching modules. The developed technology in this project is used by other fundings, including WEFO funding award for the "GaNforCS" project, a £1.8M funding over 3 years to develop a wafer level RF GaN technology, major EPSRC award EP/S024441/1, EP/P006973/1 and EP/P00945X/1. Further, interaction with major key industry (Leonardo, TNO, CSA Catapulte, TNO) via 4 PhD sponsored research projects. In addition, the developed RF GaN technology in this award is now used to develop chemical and biosensor, a project funded by MRC CiC "Super-sensitive quantitation of Extracellular Vesicles in Bio-fluids, using a novel Gallium Nitride (GaN) High Electron Mobility Transistor-based biosensor" in collaboration with Cardiff University medical School. |

| Description | The technology and finding from this award were widely and effectively used. Here are key examples, establishing industry relationship with compound semiconductor UK industry and end users of compound semiconductor chipset; this was done via grant funding applications as a PI. Samples examples, Innovate UK grant proposal jointly with The Compound Semiconductor Centre (CSC) & IQE in Cardiff. WEFO funding award for the "GaNforCS" project, a £1.8M funding over 3 years to develop a wafer level RF GaN technology. the "GaNforCS" project included 11 strong industry partners in working closely developing RF GaN industry-based technology and provided substantial matched contribution The "GaNforCS" project industry partners including IQE, Leonardo, SPTS, MBDA, CSC, IconicRF, Newport Wafer Fab, CSA Catapult. The finding technology is currently used on other major EPSRC award where I am involved as Co-I, this including, EP/S024441/1, EP/P006973/1 and EP/P00945X/1. Further, in research , 4 PhD scholarship fundings was secured as result of the technology developed in this award, this includes Leonardo, TNO, CSA Catapulte, TNO. In teaching, 2 practical teaching modules I have developed, where we used the technology developed applied by the students to fabricated and test RG GaN HEMT. CPD courses based on the finding of this award were developed and provided to major compound semiconductor industry such as IQE, SPTS and Newport Wafer Fab. Some of the technology I have developed has now been used many research groups at Cardiff University. Further, the key commercial aspects of my technology have now been taken by CSC and Institute of compound semiconductor at Cardiff University, the commercial portal to our nanofabrication facility. |

| Results and Impact | The frequency range from around 100 GHz to 1 THz provides opportunities for high data rate communications and high resolution imaging systems, but the so-called "THz gap" poses a range of interesting scientific and technological challenges. This half-day workshop will pull together results from several current projects in this field, highlighting recent advances and identifying some of the remaining challenges. |
