The devices are diodes composed of an emitting electrode and an extractor electrode: the emitting electrode is a monolithic array of digital light projection (DLP)-printed solid, conical, polymeric needles covered by a conformal layer of hydrothermally grown zinc oxide (ZnO) nanowires as wicking material, while the extractor electrode is a stainless-steel plate with an array of apertures that matches the pattern of the array of needles. Devices with 1, 7, and 19 2.5 mm-long, $sim 100 mu mathrm{m}$ tip diameter needles (2.1 mm pitch), covered with a forest of $1.2 mu mathrm{m}$ long, 150 nm diameter ZnO nanowires, were designed, fabricated, and characterized in vacuum (∼10−6 Torr) in a triode configuration (i.e. with an external collector electrode) in the negative polarity. Devices emit up to ∼86% of the current produced by the emitting electrode, and attain peremitter currents as high as $15 mu mathrm{A}$ –a tenfold larger than cleanroom-microfabricated counterparts.","PeriodicalId":6776,"journal":{"name":"2020 IEEE 33rd International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"35 1","pages":"598-601"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83128324","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}

Four micro-acoustic filters are periodically modulated by RF switches to break the reciprocity. The use of high-Q micro-acoustic filters significantly reduces the modulation frequency (14 MHz) compared to previous demonstrations based on transmission lines (e.g., 333 MHz in [1]). The low modulation frequency translates to an ultra-low power consumption (202 uW, 3600 times smaller than [1]) and one of the highest linearity ($mathrm{P}1mathrm{dB}=31 mathrm{dBm}$) reported for magnet-free circulators. Furthermore, compared to the more conventional differential configuration, this quad configuration shows advantages in terms of intermodulation products (IMPs) suppression for all the in-band IMPs, guaranteeing a pseudo-linear-time-invariant (pseudo-LTI) operation. Furthermore, the isolation of the circulator is further improved by an additional cancellation circuit, achieving more than 50 dB of isolation in a 10MHz bandwidth (BW). This high level of isolation enables the use of this magnet-free circulator in full-duplex radio, which requires large level of self-interference suppression between the transmitter and the receiver nodes.","PeriodicalId":6776,"journal":{"name":"2020 IEEE 33rd International Conference on Micro Electro Mechanical Systems (MEMS)","volume":"69 1","pages":"1270-1273"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83193307","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}
