Electron bombardment induced defect states in p-InPJournal of Electronic Materials - Tập 12 - Trang 423-432 - 1983
M. Levinson, H. Temkin, W. A. Bonner
A deep level transient spectroscopy (DLTS) study has been made of 1 MeV electron bombardment induced defect states in the lower half band gap of LEC grown Zn doped p-InP. One state was observed in the unirradiated material with a hole emission activation energy H of 0.15 eV. Irradiation resulted in two new states with H of 0.34 and 0.58 eV, and introduction rates dNt/dϕ of 1 and 0.04 cm−1, respect...... hiện toàn bộ
Effect of Silanization on the Magnetic and Microwave Absorption Properties of SrFe12O19 Nanostructure ParticlesJournal of Electronic Materials - Tập 48 - Trang 5209-5217 - 2019
Mostafa Mehdipour, Mehdad Fathi, Sina Ariae, Hooman Shokrollahi
Strontium ferrite nanostructure particles (SrFe12O19), which have a ferrimagnetic nature, were synthesized by a co-precipitation process of chloride salts using a sodium hydroxide solution. The resulting precursors were heat-treated in a furnace at 1100°C for 4 h. After cooling in the furnace, the nanostructure particles were silanized using 3-methacryloxypropyltrimethoxy silane molecules. After a...... hiện toàn bộ
Synthesis and Performance of Tungsten Disulfide/Carbon (WS2/C) Composite as Anode MaterialJournal of Electronic Materials - Tập 47 - Trang 251-260 - 2017
Zhengyong Yuan, Qiang Jiang, Chuanqi Feng, Xiao Chen, Zaiping Guo
The precursors of an amorphous WS2/C composite were synthesized by a simple hydrothermal method using Na2WO4·2H2O and CH3CSNH2 as raw materials, polyethylene glycol as dispersant, and glucose as the carbon source. The as-synthesized precursors were further annealed at a low temperature in flowing argon to obtain the final materials (WS2/C composite). The structure and morphology of the WS2/C compo...... hiện toàn bộ
Thermoelectric System Absorbing Waste Heat from a Steel LadleJournal of Electronic Materials - Tập 47 - Trang 3238-3247 - 2018
Baiyi Lu, Xiangning Meng, Miaoyong Zhu, Ryosuke O. Suzuki
China’s iron and steel industry has made great progress in energy savings and emission reductions with the application of many waste heat recovery technologies. However, most of the medium and low temperature waste heat and radiant waste heat has not been effectively utilized. This paper proposes a thermoelectric system that generates electricity by absorbing the radiant heat from the surface of s...... hiện toàn bộ
Substrate-Removed HgCdTe-Based Focal-Plane Arrays for Short-Wavelength Infrared AstronomyJournal of Electronic Materials - - 2008
E.C. Piquette, D.D. Edwall, H. Arnold, A. Chen, J. Auyeung
Removal of the CdZnTe substrate offers several performance benefits for near-infrared (NIR, 1.7 μm) and short-wave infrared (SWIR, 2.5 μm) focal-plane arrays (FPAs). Among these are visible wavelength detection, improved infrared sensitivity and uniformity, and greatly reduced susceptibility to the effects of ionizing radiation. Data for substrate-removed NIR FPAs fabricated for the Wide Field Cam...... hiện toàn bộ
Analysis of Thermal Losses for a Variety of Single-Junction Photovoltaic Cells: An Interesting Means of Thermoelectric Heat RecoveryJournal of Electronic Materials - Tập 44 - Trang 1809-1813 - 2014
Bruno Lorenzi, Maurizio Acciarri, Dario Narducci
Exploitation of solar energy conversion has become a fundamental aspect of satisfying a growing demand for energy. Thus, improvement of the efficiency of conversion in photovoltaic (PV) devices is highly desirable to further promote this source. Because it is well known that the most relevant efficiency constraint, especially for single-junction solar cells, is unused heat within the device, hybri...... hiện toàn bộ
Superconducting and Transport Properties of (Bi-Pb)-Sr-Ca-Cu-O with Nano-Cr2O3 AdditionsJournal of Electronic Materials - Tập 36 - Trang 1648-1651 - 2007
Kong Wei, R. Abd-Shukor
The effect of nano Cr2O3 additions in (Bi, Pb)-Sr-Ca-Cu-O superconductors using the coprecipitation method is reported. Nano Cr2O3 with 0.1, 0.3, 0.5, 0.7, and 1.0 wt.% were added to the (Bi, Pb)-Sr-Ca-Cu-O system. The critical temperature (T
c) and transport critical current density (J
c) were determined by the four-point probe technique. The phases...... hiện toàn bộ
Self-Assembled ZnO Nanosheet-Based Spherical Structure as Photoanode in Dye-Sensitized Solar CellsJournal of Electronic Materials - Tập 47 - Trang 1993-1999 - 2017
Mohsen Ameri, Meysam Raoufi, M.-R. Zamani-Meymian, Feridoun Samavat, M.-R. Fathollahi, Ezeddin Mohajerani
High surface area and enhanced light scattering of ZnO nanosheet aggregates have made them a promising active layer candidate material for fabrication of nanostructure dye-sensitized solar cells. Here, we propose a facile preparation method of such ZnO nanosheet structures, and in order to verify their applicability as photoanode material for dye-sensitized solar cells, we employ morphological, op...... hiện toàn bộ
