While emphasis has been placed on coherent heterojunctions for high speed device structures, the use of mismatched layers unstrained via misfit dislocations has been limited. Yet, in certain cases, the misfit dislocated layer can be advantageous. For example, in the growth of GaAs on Ina.53 GaO.47 As it has been shown that the misfit dislocations can be isolated to the GaAs interface region sug...

mrs method is one of the new geophysical methods that directly detects the groundwater. by using this method, one can determines some parameters of aquifer (porosity, permeability and transmissivity). the purpose of this research is the application of mrs method in the conductive ground. combination of mrs and rs method is used for better detection of the aquifer in the region of abyek located ...

Solution-processed black phosphorus quantum-dot-based resistive random access memory is demonstrated with tunable characteristics, multilevel data storage, and ultrahigh ON/OFF ratio. Effects of the black phosphorous quantum dots layer thickness and the compliance current setting on resistive switching behavior are systematically studied. Our devices can yield a series of SET voltages and curre...

in this paper, fourteen mt stations along a profile perpendicular to the main geological structure were used in order to identify the geology of sabalan geothermal field including the extension of the surface cap-rock and clay-cap layers. the mt data collected between 1-8192 hz is of useful quality and provides good control on the surface layers in many areas. it means that reliable modeling sh...

Nanocrystalline n type ZnO thin films were deposited on SiO2-coated (0.4 μm) p-Si substrates (10-20Ω-cm, 400 μm) by a low cost chemical deposition technique to fabricate ZnO-based resistive sensors for methane detection. The nanocrystalline ZnO needle like structures were grown on RCA cleaned p-Si substrates by successive immersion (100-200 times) into a Sodium

This paper describes two new types of neural networks. Firstly, a neural implementation of a resistive grid for path planning. Its advantages and limitations are discussed using the example of a 2-joint robot arm. Two of the limitations are the jerkiness of the movements and the inaccurate end-position. Secondly, as a solution to these two problems, a new type of sequence learning neural networ...

Copper electrodes with a micromesh/nanomesh structure were fabricated on a polyimide substrate using UV lithography and wet etching to produce flexible transparent conducting electrodes (TCEs). Well-defined mesh electrodes were realized through the use of high-quality Cu thin films. The films were fabricated using radio-frequency (RF) sputtering with a single-crystal Cu target--a simple but inn...
