This paper represents the lowest growth temperature for silicon nano-wires (SiNWs) via a vapour-liquid-solid method, which has ever been reported in the literature. The nano-wires were grown using plasma-enhanced chemical vapour deposition technique at temperatures as low as 150°C using gallium as the catalyst. This study investigates the structure and the… (More)
A major limiting factor in the performance of MIMO-CDMA systems is multiple access interference (MAI) which can reduce the system capacity as well as bit error rate (BER). Thus, statistical characterization of MAI is vital in analyzing the performance of such systems. Since, the statistical analysis of MAI in MIMO-CDMA is quite involved especially in the… (More)
A decision feedback equalizer (DFE) utilizes the previous detector's assessment to get rid of the inter-symbol interference (ISI) on the received symbols. It is well analyzed in the literature that the DFE performs better than the linear equalizer when the ISI is sever because of its inherent nonlinear nature. Equalization of wireless multiple-input… (More)
A new silicon strip detector has been designed and constructed for a fixed target experiment at CERN. The system of about 30,000 channels is equipped with SVX chips and read out via a double buffer into FASTBUS memory. Construction and performance during the actual data taking run are discussed.
In this paper, we describe an all organic molecular memory device that combines the advantages of molecular and organic electronics. We accomplish this by combining C 60 molecules with poly(4-vinylphenol) (PVP) and co-dissolving them in iso-propanol. The current-voltage measurements show a large hysteresis in the blend devices, in contrast to pure PVP… (More)
We describe the construction and performance of a hodoscope consisting of 127 hexagonal scintillating tiles covering hermetically a surface of about 1 m diameter. Each tile is read out on one face by 5 wavelength shifting (WLS) bres that are embedded and glued into the surface of the scintillator. The bres serve the double purpose of primary light… (More)
The work described in this paper focuses on the utilisation of silicon nanowires as the information storage element in flash-type memory devices. Silicon nanostructures have attracted attention due to interesting electrical and optical properties, and their potential integration into electronic devices. A detailed investigation of the suitability of silicon… (More)
