A novel metal-induced lateral crystallization (MILC) technique has been applied to the formation of polycrystalline silicon (poly-Si) with greatly enhanced material characteristics. Compared to conventional poly-Si, MILC poly-Si gives rise to much improved performance not only in sensors but also in thin film transistors. A variety of sensing and electronic devices can be realized simultaneously on MILC poly-Si, thus making MILC an enabling technology for integrated silicon micro-machining.

<title>Character recognition by synergetic neural network based on selective attention parameters</title>

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2003)

Mingxiang Wang Yulong Mo Junli Ma

In this paper a learning algorithm of synergetic neural network based on selective attention parameters is proposed. According to the mechanism of the Human Visual System (HVS), the weight matrix of synergetic neural network can be obtained by multiplying the prototype matrix by selective attention parameters. Two selective attention models based on the human visual system are put forward in this paper. The comparative experiments between the traditional algorithm SCAP and the new method we proposed in the application of recognizing the real gray images of numeric and alphabetic characters are done. And the results show that our method can improve the synergetic neural network's recognition performance and be more suitable to human visual system.

From "Cultural Imperialism" To "Intercultural Communication"

Journal of Anhui Tv University (2005)

Mingxiang Wang

This essay will analyze two items, which are regarded as two different thoughts in communication:cultural imperialism and Intercultural communication. And the new law of mankind's in the new era will be revealed critically. These two theories of emerged in different backgrounds. The theory cultural imperialism is a kind of criticism with sympathy in post-colonialism era. However, when the process of globalization has been going further and taken into shape gradually, different forms get in touch with each other more frequently, and keep the touch more closely. And they more and more rely on each other, know each other and respect each other. The theory cultural imperialism is bound to be criticized. The theory Intercultural communication is based on the grasp of new realities, emphasizing the different forms should conscientiously take the rational attitude to observe others and introspect themselves, and considering equality and freedom as the mankind's common aim of development.

Analysis of the Meyer-Neldel Rule Based on a Temperature-Dependent Model for Thin-Film Transistors

IEEE Transactions on Electron Devices (2016)

Zhiyuan Han Mingxiang Wang

Based on the Pao-Sah model and considering the double exponential distribution of traps density of states (DOS) in the bandgap, a unified drain current model is derived for thin-film transistors (TFTs). It is verified by fitting experimental I-V characteristics of both a-InGaZnO TFTs and two types of polycrystalline Si TFTs of different technologies, measured at different drain voltages and temperatures with a set of model parameters independent of temperature. Temperature dependence of TFT subthreshold current follows the well-known Meyer-Neldel rule (MNR). It is clarified that the proposed I-V model is inherently consistent with the MNR, without any intentionally introduced assumptions or parameters. Key parameter, the MN energy, is associated with the inverse slope of the deep traps DOS distribution, while another key parameter, the activation energy, is the averaged energy difference between the band edge and the quasi Fermi-level along the channel depth.

Enhanced Negative Bias Stress Degradation in Multigate Polycrystalline Silicon Thin-Film Transistors

IEEE Transactions on Electron Devices (2017)

Dongli Zhang Mingxiang Wang Huaisheng Wang Yi-Lin Yang

In this brief, a negative bias stress (NBS) induced degradation in n-type multigate polycrystalline silicon (poly-Si) thin-film transistor (TFT) is investigated. It is observed that after NBS the transfer characteristic curves shift to the negative gate bias direction and multigate TFTs degrade more than the single-gate TFTs with the same effective channel length. The observed degradation phenomenon is explained with short channel effect that is resulted from the diffusion and distribution of hole carriers in the channel, which are generated in the source/drain depletion region and swept into the channel when the junctions are reversely biased during NBS. Pronounced NBS degradation caused by increased hole carriers in the channel is also verified in NBS experiment with light illumination.

<title>Applied method of license plate binarization based on histogram analysis</title>

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2001)

Mingxiang Wang Yu L. Mo Junli Ma

The binarization of license plate image is one of the key techniques of car license plate recognition (CLPR) system and its results influence the accuracy of the segmentation of characters and their identification directly. In this paper, by analyzing the limitations of Otsu's method and Bernsen's method, a practical method of license plate binarization based on histogram analysis is proposed. In this method, the feature that the percentage of the character area is always less than that of background is presented to distinguish the style of plate. Then a global thresholding method, Doyle's method, is used to threshold the plate image. By counting over 8,000 pieces of plate images, the accuracy is nearly 99%. Only those pictures which are badly polluted or with very low resolution cannot be binarized correctly. The experimental and field-tested results show that our method has higher accuracy, higher speed and better binarization effect. The method has been applied in our CLPR system successfully.
