Hybrid polyaniline (PANI) based composites incorporating zinc sulfide (ZnS) nanoparticles (NPs) have been synthesized by using chemical oxidation technique. Schottky junction is constructed by depositing Polyaniline-zinc sulfide nanocomposite (PANI-ZnS NCs) on Au electrode. The results were compared with pure polyaniline. The I–V characteristics of the PANI-ZnS NCs hete...

In this work we present a Schottky diode grid mixer suitable for mixing or detecting quasi-optical signals. The mixer is a planar bow-tie grid structure periodically loaded with diodes. A simple transmission line model is used to predict the reflection coefficient of the grid to a normally incident plane wave. The grid mixer power handling and dynamic range scales as the number of devices in th...

This letter presents a novel C-band rectifier that is capable of handling high input power. The consists Schottky diode, an impedance matching circuit with compensation microstrip structure, and output filter harmonic suppression ripple smoothing. experimental results indicate the yields conversion efficiency exceeding 70% peak 74.1% over wide power range 20 to 26 dBm (6 dB) at 5.8 GHz, utilizi...

Silicon carbide (SiC) is the perfect cross between silicon and diamond. The crystal lattice of SiC is identical to silicon and diamond, but, exactly half the lattice sites are occupied by silicon atoms and half by carbon atoms. Likediamond SiC has electronic properties superior to silicon, but, unlike diamond it is also manufacturable. The thermal leakage current (dark current) in SiC is sixtee...

The software support for simulation of electrical circuits has been developed for more than sixty years. Currently, the standard tools for simulation of analogous circuits are the simulators based on the open source package Simulation Program with Integrated Circuit Emphasis generally known as SPICE (Biolek 2003). There are many different applications that provide graphical interface and extend...

Generally, glow-discharge detectors (GDD), acting on miniature neon indicator lamps, and Schottky diode serve as efficient, fast, room-temperature millimeter wave (MMW)/THz detectors. Previous studies GDD implemented a repetition of terahertz sources, low-power radiation, showed good results in terms detection, responsivity, noise-equivalent power. This paper presents comparison between detecto...

Schottky barrier diodes can be used as direct detectors throughout the millimeterand submillimeterwave bands. When the diodes are optimized to have a low forward turn-on voltage, the detectors can achieve excellent frequency response and bandwidth, even with zero-bias. This paper reports on the characterization of VDI’s zerobias Schottky detectors. Responsivity typically ranges from 4,000 V/W a...
