The paper proposes a SPICE compatible model of a dual-gate bilayer graphene field effect transistor (FET) that models the channel's dependence to temperature. The model ensures Jacobian continuity across the various regions of operation for efficient implementation in the Berkeley SPICE simulator. Using a validated tr…
For polymer solar cells, the efficiency loss is caused by considerable carrier recombination in active layer based on low carrier diffusion length or low carrier collection. Here, to increase the carrier collection, ZnO nanorods are inserted between thin ZnO seed layer and active layer. Consequently, the carrier trans…

The catalytic behavior of a series of cobalt catalysts supported on zirconia in the selective catalytic reduction (SCR) of NO has been studied using propane as reducing agent. The catalysts were characterized by Raman Spectroscopy, Temperature Programmed Reduction (TPR), Diffuse Reflectance Spectroscopy UV-Vis (DRS) a…
In this paper, we report fabrication and photoelectrochemical properties of nanocomposites MoS2-TiO2prepared by high energy ball milling. Scanning electron microscope with energy dispersive x-ray spectroscopy (SEM-EDX) has been applied for analyzing morphology and elements distribution of the nanocomposites. The two i…

The spectral performance of an EDS detector is almost universally described by measuring the Mn kalpha line at an x-ray collection rate of a few thousand counts per second. In many cases, this is the only metric cited in describing detector performance. The rationale is mainly historic and based on the ready availabil…

In the design of fault-tolerant or fail-safe systems, detailed knowledge of potential failure processes is required. One failure mode in electrical machines is an inter-turn, or turn-to-turn short-circuit, which can cause very large local heating and subsequently, progression of the fault. This paper experimentally de…

We present a new technique for designing a broadband, low-profile, multi-beam high-gain antenna. In order to achieve high-gain multi-beam operation with a wide field of view, the antenna uses multiple feed elements placed on the focal plane of a planar microwave lens. The constituting elements of the lens are unit cel…

This work describes the studies of the behavior of the electrodes of high voltage compressed capacitor using finite element method (FEM). This study is important to determine the voltage coefficient and evaluate the dependence of the capacitance with the voltage change. It is estimated the displacement of low-voltage…

Sharp and intense emission from the Si-V luminescent center in diamond grown on Si is observed. Possibility of the Si-V luminescence center as a light source for integrated quantum photonics on Si chip is suggested.
