It is therefore expected to be highly efficient for high-power RF devices. We identify hole carrier doping in diamond using nitrogen dioxide (NO2). Furthermore, we find that an aluminum oxide (Al2O3) passivation layer greatly improves the thermal stability of the hole channel. These two technologies enable us to create thermally stable high-performance diamond field-effect transistors (FETs). The diamond FET shows a maximum IDS value of -1.35 A/mm, cut-off frequencies fT and fMAX of 35 GHz and 70 GHz, respectively, and an RF output power density of 2 W/mm at 1 GHz.","PeriodicalId":183218,"journal":{"name":"2016 IEEE Compound Semiconductor Integrated Circuit Symposium (CSICS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117006481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents the design of a wideband RF pre-amplifying buffer, innovated for very low dropout and low power complementary operation in heterojunction technologies affording only depletion type devices. A simple, passive bias level shifting technique is also incorporated to facilitate interfacing the digital modulator in silicon substrate with the PA in III-V wafer. In order to experimentally validate the concepts, the proposed driver is employed for driving an S-band single-ended class-E PA as well as for its differential version, modified to switch over S and C bands, in 130 nm GaAs pHEMT technology. The output powers of the differential amplifier are combined using on-chip transformer balun. Test results of both chips demonstrate that the implemented drivers consume less than 4% of the overall PA efficiencies, wherein the buffer responds linearly to the wideband input pulses when tested alone.","PeriodicalId":183218,"journal":{"name":"2016 IEEE Compound Semiconductor Integrated Circuit Symposium (CSICS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114265905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

UV measurements from both sides of the wafer reveal an unexpected gradient between the tensile stress from the free GaN surface (~0.86 GPa) and the GaN/Diamond interface (~0.23 GPa). This gradient is understood through non-uniformities in the material along the growth direction of the layers, with relaxation attributed to threading dislocations.
