The rapid progress of interest in carbon nanotubes research have been improved with a development of sensitive tools for their observation and characterization. In this work Raman spectroscopy and atomic/electric force microscopy (AFM/EFM) have been successfully applied for studying electrical and structural properties of multiwall carbon nanotubes (MWNT). The combination of these methods (Rama...

in this paper electrical conductivity measurements and optical investigations takes place in aot/ heptane/ (water or aqueous) systems. the water in oil system prepared with adding water in 50% by weight of aot/ heptane solution.  in other systems instead of water, aqueous solutions of 1) zinc acetate and water 2) potassium hydroxide and water were used. in each phase, the trend of the electrica...

La₁-xSrxTiO3+δ (LST) has been studied in many fields, especially in the field of microelectronics due to its excellent electrical performance. Our previous theoretical simulated work has suggested that LST has good dielectric properties, but there are rare reports about this, especially experimental reports. In this paper, LST was prepared using a solid-state reaction method. The X-rays diffrac...

With the purpose of understanding a well-documented RPC ageing phenomenon, consisting of a gradual increase of the plate resistivity for chambers working at high rate, we carried out a systematic study on the electrical conduction properties of phenolic–melaminic electrode plates. A number of small size sample plates were kept under intense electrical current at fixed voltage, to simulate a hig...

This thesis examines the electrical and mechanical properties of graphene sheets. We perform low temperature electrical transport measurements on gated, quasi-2D graphite quantum dots. In devices with low contact resistances, we use longitudinal and Hall resistances to extract a carrier density of 2-6 x 10 11 holes per sheet and a mobility of 200-1900 cm 2 /V-s. In devices with high resistance ...

Cu3Ge has been pursued as next-generation interconnection/contact material due to its high thermal stability, low bulk resistivity and diffusion barrier property. Improvements in electrical performance and structure of Cu3Ge have attracted great attention in the past decades. Despite the remarkable progress in Cu3Ge fabrication on various substrates by different deposition methods, polycrystall...

2014 MOS transistors are used for radiation dosimetry. The sensitivity obtained is ranging between 20 mV/ Gray (SiO2) and 1,5 V/Gray (SiO2). Good linearity and stability of the transistor response is obtained. Revue Phys. Appl. 21 (1986) 283-287 AVRIL 1986, Classification Physics Abstracts 73. 60D

Goldfish hypothalamic neuroendocrine cells have been investigated with intracellular recordings. The cells showed resting potentials of 50 mv and action potentials up to 117 mv followed by a long lasting and prominent diphasic hyperpolarizing afterpotential. The action potential occurred in two steps indicating sequential invasion. "Total" neuron (input) resistance was measured to be 3.3 x 10(7...
