Since the water splitting reaction using semiconductor electrode reported by Fujishima et al. in 1972 [1], there is increasing interest in the development of metal oxide photocatalysts for environmentally friendly applications such as air purification [2], hydrogen production via water splitting [3] and the removal of organic molecules from water [4]. Recently, photocatalyst thin film has aroused growing interests instead of a powder type of photocatalyst. Photocatalyst film can be deposited…

Supplemental information for “Colloidal Type-II CdS/ZnSe NCs : Synthesis, Electronic Structures, and Spectroscopic Properties” S.A. Ivanov, A. Piryatinski, J. Nanda, S. Tretiak, D. Werder, V. I. Klimov Theoretical model. To describe quantum states in a spherically symmetric Type-II core/shell nanocrystals (NC) characterized by the core radius R and the shell width H, we use effective mass approximation. We assume the existence of single energy bands for both electrons and holes. This assumption…

Dipole-dipole array has wide using in resistivity/I.P. surveys because of the low E.M. coupling between the current and potential circuits. The arrangement of the electrodes is shown in Figure( )., Electrodes c1 and c2 are separated by a distance (a), and electrodes p1 and p2 are separated by a distance (b). the distance between the potential electrodes pair c1-c2 is the same as the distance between the potential electrodes pair P1-P2 and the distance between the centers of the respective…

30, 58-61]. The VRH model proposed by Vissenberg and Matters model that considers the hopping percolation of thermally activated carriers between localized states is the most model used for describing charge transport in the disordered organic semiconductors and modeling the electrical characteristics OTFTs [27, 58]. Indeed, the notion of VRH implies that a free carrier either may over a long distance with low activation energy or hop over a short distance with high activation energy [22-25,…

noise in semiconductors and metal films. According to this model, the PSD of flicker noise is given by, S(f) = γHV 2 Ncf α Where Nc = ncΩ is the number of free charge carriers in the specimen,nc is the charge carrier density and Ω is the volume of specimen.γH is the Hooges constant, a parameter which characterizes the noise levels of a particular system. The initial value of gamma is assumed as 2 ∗ 10−3 . Experimental evidence supporting this model is the noise signals in semiconductors, which…

Semiconductor devices have transformed the way that we live by making tasks easier and more efficient than before. By utilizing the opinions of different professionals in the field about their affect on society, I want to investigate the different aspects of semiconductor devices. The question of will the accumulation of both the positive and negative outputs of the semiconductor industry lead to the need of advancing technology that is independent of the semiconductor. This is important to me…

INTRODUCTION 1.1 :R[1] MEMS (Micro Electro Mechanical Systems) are innovative microfabricated devices with critical dimensions in the range of 1 to 1000µm. These devices are electro-mechanical structures whose complexity varies from a simple actuator to a highly complex electromechanical system performing a wide variety of sensing and control. Introduced in the early 60’s the development of this technology has been growing tremendously. It has been the pioneer in sensor and other applications.…

situations in information technology that possess an ethical dimension? With the knowledge I have gained in this course the manner in which I approach an IT ethical issue will be with better understanding of how ethical issues can impact an IT company. With have a better understanding of what an ethical issue is and the problems they can present in the IT field I believe I will have more courage to stand up and speak out about and issues that I find that could be considered unethical. My newly…

began in the early 1900’s as a company motivated to produce washers with a wringer attachment. The innovation soon caught the attention of identical industries, driving the company to borrow funds to expand and increase production. However, in the midst of the Great Depression, the company was faced with inadequate sales to pay back the money borrowed from Sears. Although with a workable agreement and a stock exchange, the loan was forgiven. Soon, both companies expanded the Kenmore line of…

a concept where by companies integrate social and environmental concerns in their business operations and in their interaction with their stakeholders on a voluntary basis”. CSR is based on the concept of do “good business” for a good society- today and for the next generations. The main aim of using CSR in business is to increase the profits with thinking of society welfare. For the business society is essential who demands.CSR demands a symmetric change. For this, companies need stronger…
