Anomalous photocurrent observed in an Fe–ZnS:Fe Schottky diode

Anomalous Transient Photocurrent

The operating principle in conventional optoelectronic devices is based on steady-state photocurrent. In these devices, photogenerated carriers have to travel long distances across the devices. Various dissipation mechanisms such as traps, scattering and recombination dissipate these carriers during transport, and decrease device response speed as well as optoelectronic conversion efficiency, e...

Schottky Diode Graphene Based Sensors

In this paper, we aim to demonstrate a novel scheme for integration of nanostructured semiconductor Graphene Oxide (GO) shottky diodes on flexible substrate for a wide range of sensing applications. The platform introduces a novel flexible GO/Pt/n-Si and GO/Pt/SiN composite structures which provides excellent optical and electrical properties, while maintaining an acceptable mechanical, biocomp...

TeraHertz Schottky-Diode Balanced Mixers

We report on the first THz balanced mixer/upconverter using a Schottky diode MMIC chip. Using an optically pumped laser at 1562 GHz as an LO source with a coupled power of about 1 mW, and 1 mW input at an IF frequency of 10 GHz, we obtained a sideband output power of 23 uW (sum of two sidebands). As a mixer, at an LO of 1621 GHz, we obtain a conversion loss of 12.4 dB DSB and a noise temperatur...

An Heterojunction Schottky Barrier Diode with RTD Emitter

The possible application of Schottky diodes as detector elements in receivers and image sensing systems operating in the THz frequency range has been demonstrated in the literature. In addition to metal-semiconductor (M-S) Schottky diodes, the use of heterojunction Schottky barrier diodes for detection and mixing applications has also been explored. Such diodes require lower d.c. bias voltages,...
