In this work, we study the effect of random dopants on characteristic fluctuations in 16-nm-gate lateral asymmetric channel (LAC) MOSFET devices. Devices with high channel doping concentration near the drain-end (the so-called inverse LAC; inLAC) can effectively improve DC characteristics fluctuation induced by random dopants. We have observed that the DC characteristic of the proposed inLAC MOSFET is less sensitive to random dopant, compared with conventional planar and LAC devices. Consequently, the inLAC MOSFET is further optimized for the best DC characteristic fluctuation reductions.","PeriodicalId":308501,"journal":{"name":"2010 IEEE International Conference on Semiconductor Electronics (ICSE2010)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133006898","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}

Good gate controllability for typical current-voltage (I-V) characteristics of FET is observed. This result shows that an undoped-AlGaN surface at the open-gate area is effectively controlled by the isolated gate voltage via chemical solution. Stable pH sensing operation in aqueous solution is observed where this device exhibits a high linear sensitivity of 3.88 mA/mm/pH at drain-source voltage, VDS = 5 V. Due to the occurrence of large leakage current, the Nernstian's like sensitivity is not observed. It is also found that the device is sensitive to changes in electrostatic boundary conditions of the polar liquids. This indicates that the change in dipole moment in each liquid causes the potential change at AlGaN surface.","PeriodicalId":308501,"journal":{"name":"2010 IEEE International Conference on Semiconductor Electronics (ICSE2010)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133692420","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}

Key motivation of the design is to reduce computational complexity and performance enhancement. Fuzzy intelligent technique is used to tackle inherent ambiguities in different handwriting recognition. This system is capable of recognizing handwritten characters such as one segment, distinguish characters and symbols. The algorithm of the HR system is developed in Matlab first, followed by Fuzzy perception. The model is extensively tested with different sets of handwriting to verify the correct functionality of the system. The Matlab codes are then translated into VHDL using Quartus II from Altera. Simulation results showed clear evidence that fuzzy based HR system is capable of emulating different human reading. Comparison between simulation results in Matlab and VHDL is presented to validate the developed HR system. Quartus Integrated Synthesis (QIS) is used to synthesize the hardware architecture. The system runs at 4.31 MHz with propagation delay of 231 ns. The developed HR hardware system is applicable in automating document-processing task such as mail sorting, check reading in Personal Digital Assistant (PDA), and tablet PCs etc.","PeriodicalId":308501,"journal":{"name":"2010 IEEE International Conference on Semiconductor Electronics (ICSE2010)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115438022","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 energy spectrum is quantum (or digital) in other two cartesian directions where electron waves are standing waves. In the quantum limit, an electron (hole) occupies the lowest (highest) digitized/quantized state giving it a distinct 1D character. The energy E =vF | k | in carbon-based devices is linearly dependent on the wave vector k, where vF ≈ 106 m/s. This is in direct contrast to parabolic character E =ħ2 k2/2m∗ in solids with effective mass m∗, for example in silicon NWs. The probability of changing wavevector from +ve to −ve direction through scattering or vice versa is greatly reduced and hence high mobility is expected, especially at low temperatures. The crucial outcome of this paper is the answer to the question: Does a higher mobility leads to a higher ultimate saturation velocity? The distribution function in a high electric field ε is then naturally asymmetrical affected by the energy ±qεℓ absorbed or emitted by a carrier of charge q during its ballistic flight in a mean free path ℓ. The ultimate drift in response to a high electric field results in unidirectional streaming of the otherwise randomly-oriented velocity vectors in equilibrium. The high-field drift limited by the intrinsic velocity is ballistic, unaffected by scattering-limited processes. The ultimate velocity is further limited to an emission of a quantum either in the form of an optical phonon or a photon by an electron excited to a higher state by the applied electric field. The velocity does not depend on scattering parameters. Ballistic processes as a result of reduction in length of a CNT or NW below the scattering-limited mean free path ℓ in the quasi-free direction are also discussed.","PeriodicalId":308501,"journal":{"name":"2010 IEEE International Conference on Semiconductor Electronics (ICSE2010)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124054339","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}

It has been observed previously by other researchers that Mn is one of interesting dopant. This dopant inside of ZnS offers a feasible means of fine tuning band gap. Because of this property, we interested to study the effect on electrical part. Hence, the aim of this work is discussed in term of electrical dark conductivity and photoconductivity of ZnS: Mn. Zn(1−x)MnxS samples with various x values (0.05≤ x ≤ 0.35) are synthesized by using sol gel spin coating method. Surface morphology and I-V characteristics of the samples are investigated by using FE-SEM and dc electrical measurement with and without UV exposure. It is found that the average diameters are between 25 and 27 nm. The increase of Mn site doping concentration leads to an increase of the electrical dark conductivity and photoconductivity of the samples. Moreover, we have found that the current increases greater with the increment of Mn concentration by using UV source.","PeriodicalId":308501,"journal":{"name":"2010 IEEE International Conference on Semiconductor Electronics (ICSE2010)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129374373","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}

Cyclopentadienyl manganese tricarbonyl (Cp2MnT) was used as a source of Mn. The growth was conducted at varied growth temperature in the range of 625 to 700°C and V/III flux ratios between 440 and 1080. The growth rate and Mn incorporation into GaN highly depend on growth parameters. From the analysis of XRD spectra, it was found that the highest Mn incorporation into GaMnN which would produce single phase GaMnN (0002) was 6.4 % at growth temperature of 650°C. While at growth temperature of 700°C, the maximum of Mn incorporation into GaMnN films that would still produce single phase film were 3.2 %. The surface roughness of the films determined from AFM image results showing that high growth temperatures tend to improve the surface morphology of GaMnN.
