An optical electrode design is presented that theoretically allows 100% optical transmission through an interdigitated metallic electrode at 50% metal areal coverage. This is achieved by redirection of light incident on embedded metal electrode lines to an angle beyond that required for total internal reflection. Full-field electromagnetic simulations using realistic material parameters demonst...

(a) Pb and Cd start to deposit on the electrode at preconcentration potential; (b) deposited metals form multicomponent alloys with Bi; (c) Cd is first stripped from the electrode, and generates a peak current at its reduction potential, and (d) Pb is stripped off and generates anothe...

Electron emission from ceramic disks depends strongly on the shape of the front electrode. The common interconnected grid is not good for a stable emission. An electrode consisting of an ensemble of metal point-like islands within a metal ring leads to quite a stable emission. In the first case the sandwich of the continuous electrode (on one surface) and the grating (on the front surface) cons...

The electric-pulse-induced resistance switching in layered structures composed of polycrystalline Pr1-xCaxMnO3 (PCMO) sandwiched between Pt bottom electrode and top electrodes of various metals (metal/PCMO/Pt) was studied by direct current current-voltage (I-V) measurements and alternating current impedance spectroscopy. The I-V characteristics showed nonlinear, asymmetric, and hysteretic behav...

In this work the critical aspects of the process sequence developed for fabrication of hybrid polymer microfluidic systems integrating metal electrode pattern and precisely aligned microfluidic structure are discussed in details. Glass and polycarbonate were considered as primary transparent substrate materials for metal (Au, Pt) electrode deposition and the microchannels were formed in multi-l...

This paper will describe how a gate electrode formation process in a GaAs FET device was analyzed and optimized for increased CD control and product throughput. Optimizations included a new resist in the photolithography process, a new solvent and equipment type in the metal liftoff process, and a new dome structure in the metal deposition process. These process optimizations resulted in a gate...

[1] There is growing interest in the application of electrode‐based measurements for monitoring microbial processes in the Earth using biogeophysical methods. In this study, reactive electrode measurements were combined to electrical geophysical measurements during microbial sulfate reduction occurring in a column of silica beads saturated with natural river water. Electrodic potential (EP), se...

Original scientific paper In present work, thermal transport considering heat radiation by oval heat source shape and heat transfer of molten moving electrode was presented. In present paper, an analytical solution was presented by aggregating temperature increments caused by applying liquid metal and heat radiation of moving electrode. The assumptions for the study were heat source of temperat...
