Capturing the functionality of active dendritic processing into abstract mathematical models will help us to understand the role of complex biophysical neurons in neuronal computation and to build future useful neuromorphic analog Very Large Scale Integrated (aVLSI) neuronal devices. Previous work based on an aVLSI multi-compartmental neuron model demonstrates that the compartmental response in the...
We have obtained high-efficiency solar cells using 15.6 cm × 15.6 cm size wafers cut from small Si multicrystalline ingots with 30 cmØ and the height of 7.5 cm, as well as those using 10 cm × 10 cm size wafers [1]. The ingots were grown by controlling the distribution and orientation of dendrite crystals grown along the bottom of the ingots, using the dendritic casting method. The conversion efficiency...
Metal-insulator-metal (MIM) capacitors have found wide use in analog/mixed-signal IC products. However, a variety of extrinsic defects can occur during manufacture. Surface roughness and particles have been proposed as major sources of defects, but there have been no reported methods to visually elucidate how the defect interacts with its surroundings or correlation of the defect with the failure...
In this paper, we report a novel electrochemical deposition (ECD) method to fabricate silver nanoscale wires and dendrites. We carry out the electrochemical deposition (ECD) process on a small piece of Si wafer. On its surface, there are micro-scale predefined silver electrodes. We use organic solution (N,N-dimethylformamide (DMF)) instead of metal salt solution as the electrolyte. Usually the fractal...
Several experiments have been performed to evaluate the nucleation, growth, structure and microstructure of aluminum induced catalytically activated low temperature crystallization of amorphous Si. TEM and in-situ XRD investigations on hydrogenated amorphous silicon (alpha-Si:H) grown by PECVD and coated with a thin layer of aluminum on it revealed the beginning of solid state transformation of polycrystalline...
The dendrite casting method has been developed to constantly obtain high-quality Si multicrystal ingots, on the basis of our new concept to control the grain orientation and grain size. Using this method, textured high-quality Si multicrystal ingots (15cmoslash ) have been grown on the {110} or {112} upper surface of dendrite crystals. So, the Si multicrystal ingots have same grain orientation and...
