The semiconducting MoS2 as n-channel and few-layer phosphorene as p-channel have been considered as promising ultra-thin body channels for future microelectronic and optoelectronic devices. In this paper, we focus on the fundamental device properties of these 2D transistors. In the first part of the paper, we demonstrate high-performance MoS2 FETs with record drain current of 460 mA/mm and record low contact resistance of 0.5 Ω·mm enabled by molecular chemical doping of 1,2 dichloroethane (DCE). In the second part of the paper, we introduce a new p-type 2D material called phosphorene which is one monolayer of layered black phosphorus (BP). At room temperature, the few-layer phosphorene field-effect transistors with 1.0 μm channel length display a high on-current of 194 mA/mm, a high hole field-effect mobility of 286 cm2/V·s, and an on/off ratio up to 104. We demonstrate the possibility of phosphorene integration by constructing the first 2D CMOS inverter of phosphorene PMOS and MoS2 NMOS transistors and the first BP/MoS2 PN diode for photonic applications.","PeriodicalId":309722,"journal":{"name":"2014 IEEE Compound Semiconductor Integrated Circuit Symposium (CSICS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129011992","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}

At 86GHz operation, 232mW Pout with peak 28.9% PAE is observed - this corresponds to 1.21W/mm linear power density. This 2-stage amplifier has a flat S21 mid-band gain of 14-15dB, and the 1dB small-signal gain roll-off is between 66-96GHz. The large-signal Psat bandwidth is between 69.5-94GHz. This SSPA utilizes a novel, compact power cell topology developed for multi-finger HBTs, which overcomes the inability of the RF output interconnects and combiners to carry the high DC bias currents required by the HBT PA cells in the thin-film microstrip interconnect. Across the 76-94GHz bandwidth, P1dB gain compression Pout is >118mW which corresponds to ≥ 14.5% PAE; this is a relevant RF operating point where higher linearity operation may be required. This work improves upon the state-of-the-art for E-, and W-Band SSPAs by demonstrating 6x higher bandwidth (24.5GHz largesignal bandwidth) while having high PAE > 23.5%.
