For example, the T-dependent mobility μ was characterized by a peak at ~ 250 K after which point μ decreased according to μ ~ T-0.71, attributed to phonon scattering. Additionally, ϕms was found to be 29 meV at VG = 0 V which decreased as VG increased in alignment with barrier modulation theory. Finally, optoelectronic properties of our Au/Ti/WSe2 field effect transistors (FETs) were investigated by exposing the device to a tunable laser, where the photoresponsivity R was calculated to be ~ 43 A/W at an optical power of 0.786 nW. The phototransistor also showed very short response time with τrise = 10 ms, and Tfall = 3 ms. Our work demonstrates excellent potential of WSe2 as a promising 2D semiconductor for high speed electronics and opto-electronics.","PeriodicalId":6787,"journal":{"name":"2020 IEEE 15th International Conference on Nano/Micro Engineered and Molecular System (NEMS)","volume":"1 1","pages":"18-21"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90630364","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}

Fulfillment of this promise, however, has been impeded by ineffective \"sample-to-droplet\" interfaces with shortcomings ranging from significant waste of sample volume, limited scalability of the number of samples, to lengthy idle time due to sample injection and switch. In response, we have developed a programmable nanodroplet device with a \"direct\" sample-to-droplet interface that has low sample waste, high scalability, and minimal idle time. In our device, each sample (0.8 μL) is directly spotted onto an open-to-atmosphere device inlet. The sample-to-droplet interface of our device uses programmable microfluidic valves to regulate vacuum-assisted infusion of the sample from the open inlet into the device, as well as pressure-driven generation of nanodroplets (as small as ~5 nL) from the sample with minimal waste. Our device ensures high scalability, as series of samples are simply processed by the sample-to-droplet interface in succession. Parallelization of a pair of our sample-to-droplet interfaces and effective cleaning between successive samples help minimize idle time and cross-contamination. Finally, we have integrated nanodroplet assembly and on-chip incubation capabilities in our device and have coupled our device with an in-house laser-induced fluorescence detector to achieve in-line fluorescence detection of our nanodroplets. For demonstration, we perform a cytochrome P450-based drug screening assay in 50-nL nanodroplets - a 2000-fold reduction from 100-μL benchtop reactions - in our device and achieve excellent differentiation of no-drug controls from inhibitor controls (Z′ = 0.84).","PeriodicalId":6787,"journal":{"name":"2020 IEEE 15th International Conference on Nano/Micro Engineered and Molecular System (NEMS)","volume":"3 1","pages":"255-260"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75073817","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}

The proposed sensor model was verified by the reported experimental data and it was further used for the efficient optimization of the TMCF sensor design with different key parameters: (1) the response time τc prediction, (2) the optimum distance D from microheater to thermal sensing element, (3) membrane thickness t, (4) the depth of bottom cavity h. After that, we designed and fabricated a TMCF sensor with CMOS compatible materials using MEMS technology. The measured response time of the TMCF sensors with the nitrogen flow from 0 m/s to 8 m/s was in reasonable agreement with the theoretical prediction. Therefore, this nonlinear model can be quite useful for the design and optimization of a new TMCF sensor. Moreover, the measured response time of the fabricated flow sensor (pair 1) is as good as less than 6 ms, which reveals that our developed TMCF sensor can be used for the monitoring of human respiration in the future.","PeriodicalId":6787,"journal":{"name":"2020 IEEE 15th International Conference on Nano/Micro Engineered and Molecular System (NEMS)","volume":"220 1","pages":"67-71"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89126524","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}
