Three types of two-terminal CdS nanowire devices with distinct current versus voltage characteristics were fabricated by forming Schottky and/or Ohmic contacts in a controlled manner. Argon ion bombardment of CdS nanowires increased the carrier concentration allowing the formation of Ohmic Ti–CdS contacts. Scanning photocurrent microscopy SPCM was used to explore the influence of the contacts o...
Central toroidal rotation and impurity transport coe cients have been determined in Alcator C-Mod Ohmic High Con nement Mode (H-mode) plasmas from observations of x-ray emission following impurity injection. Rotation velocities up to 3 10 m/s in the co-current direction have been observed in the center of the best Ohmic H-mode plasmas. Purely Ohmic H-mode plasmas display many characteristics si...
We investigated the electrical contact characteristics of indium tin oxide (ITO)/doped hydrogenated amorphous silicon (a-Si:H) junctions. For efficient collection of photo-generated carriers, photovoltaic and photodetector devices require good ohmic contacts with transparent electrodes. The amorphous-Si thin films were sputter deposited on ITO coated glass substrates. As-deposited p-type a-Si:H...
پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
The effect of microwave heating (MH, 65 and 75 °C for 15, 30, 60 s) on the bioactive compounds, fatty acid profile, volatile compounds orange juice-milk beverage (OJMB) was evaluated during 28 days refrigerated (4 °C) storage. Conventionally pasteurized (75 °C/15 untreated beverages were used as controls. MH-OJMB presented a lower browning index higher levels ascorbic acid, total phenolics, car...
In superconductors where the coherence length is comparable to the Fermi wavelength , the electronic levels within a vortex core are quantized, and separated by energies of the order of the superconducting gap. The absence of a continuum modifies significantly the energy dissipation due to the motion of vortices. At zero temperature , dissipation is suppressed, and the system shows non ohmic be...
the problem of combined heat and mass transfer of an electrically conducting fluid in mhdnatural convection adjacent to a vertical surface is analyzed, taking into account the effects of ohmic heatingin the presence of suction or injection. an approximate numerical solution for the steady laminar boundarylayerflow over a wall of the wedge in the presence of species concentration and mass diffus...
