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…

TI current strategy to focus in customer and involve earlier into customer’s product life cycle, differentiate itself with rivals. TI sales grow faster than industry average. The firm’s image and reputation grows stronger, TI profit margin increase and better than industry. The net profit and return on investment grow stably. The overall financial strength improves. TI can create the premium value to customer by providing additional service to help customer to solve issue and delivery when…

Interviewer: Okay Chris, thanks. One of the things that I heard mostly about SiBEAM, and I only had a chance to meet one of the founders when you guys were still in the old office, right at the integration was being announced. It was very early on and the purpose of that was to just find out about what this Silicon Image culture and it quickly became apparent within Silicon Image, their siting culture, and so now we are fast forwarding two years, and now it is Silicon Image, in Lattice and…

ELECTRONIC MANUFACTURING INDUSTRY IN SINGAPORE INTRODUCTION Singapore Electronic Industry started 50 years ago in the 1960s with its first and only TV Assembly plant in Southeast Asia. And today, Singapore Electronic Industry has become the backbone of Singapore’s economy, contributing 5.3% of the Gross Domestic Product (GDP) in 2013, 29% of total manufacturing output, and employed 80,000 workers, representing 19% of the total manufacturing labour force in Singapore (EDB, n.d). Due to the…

• Industry Structure: interdependent relation among suppliers of inputs, buyers of outputs, substitute products, potential new entrants, rivalry among competing firms. (PG 440) o Suppliers of inputs: EDA Industry mainly depends on inputs from three main suppliers – Mentor Graphics, Synopsys and Cadence Design Systems. o Buyers of outputs: Hi-Tech electronics development and manufacturing industry, PCB and semi-conductor manufacturers, aircraft industry, automotive industry, defense industry,…

MEMS when integrated with an ASIC (Application Specific Integrated Circuit) reduces the need for complex external circuitry and provides a more reliable operation. R[6]. MEMS was developed with a lot of technologies and process similar to the IC industry…
