We demonstrate the fabrication and characterization of silicon nanowire-based devices in metal-nanowire-metal configuration using direct current dielectrophoresis. The current-voltage characteristics of the devices were found rectifying, and their direction of rectification could be determined by voltage sweep direction due to the asymmetric Joule heating effect that occurred in the electrical ...

A favorable trade balance is a positive indicator for emerging economies, and rectifying imbalances paramount every country. However, fixing deficits by depreciating the currency misguided policy approach. This study refutes this myth computing elasticity of Pakistan's exports, imports, using real exchange rate. It also examines degree to which elasticities respond changing regimes rate policie...

Stereo rectification is the determination of two image transformations (or homographies) that map corresponding points on images, projections same point in 3D space, onto horizontal line transformed images. Rectification used to simplify subsequent stereo correspondence problem and speeding up matching process. Rectifying transformations, general, introduce perspective distortion obtained which...

In our earlier paper [BuK] (see also McMullen’s paper [M]), we constructed examples of separated nets in the plane R2 which are not biLipschitz equivalent to the integer lattice Z2. These examples gave a negative answer to a question raised by H. Furstenberg and M. Gromov. Furstenberg asked this question in connection with Kakutani equivalence for R2-actions, [F]. Return times for a section of ...

Inwardly rectifying K+ (IRK) channels are critical for shaping cell excitability. Whole-cell patch-clamp and single-cell RT-PCR techniques were used to characterize the inwardly rectifying K+ currents found in projection neurons of the rat nucleus accumbens. Inwardly rectifying currents were highly selective for K+ and blocked by low millimolar concentrations of Cs+ or Ba2+. In a subset of neur...

There is clear evidence that the net magnitude of negative charge at the intracellular end of inwardly rectifying potassium channels helps to generate an asymmetry in the magnitude of the current that will pass in each direction. However, a complete understanding of the physical mechanism that links these charges to current rectification has yet to be obtained. Using Brownian dynamics, we compa...

Abstract We report the van der Waals integration of micropatterned GaN light-emitting diodes (LEDs) onto foreign graphene films. micro-LEDs were selectively grown on a substrate using patterned SiO 2 mask, and then whole device structure was laterally fixed by polyimide insulator to form united layer. After fabrication, LED/graphene heterostructure piled layers typical wet transfer technique 2D...

An optoelectronic device model for organic photodetector based on bilayer structure has been presented. Drift-diffusion and optical-generation from Synopsys tool have incorporated its optoelectronics behavior discussed. The shows an outstanding rectifying under dark condition due to the different work function of electrodes. Photocurrent density 6.64 mA/cm2 is found illumination 3 W/cm2. To ana...

Recent experiments on symmetry-broken mesoscopic semiconductor structures have exhibited an amazing rectifying effect in the transverse current-voltage characteristics with promising prospects for future applications. We present a simple microscopic model, which takes into account the energy dependence of current-carrying modes and explains the rectifying effect by an interplay of fully quantiz...
