Micro-and nanowires obtained by replikations of track membranes for mass-spectrometry

摘要：

Specially prepared porous matrixes (with through and dead-end pores of cylindrical or conical forms) were used as the tem plates for making ensembles of microwires. The process of electrodeposition of metal (Cu) into these pores was investigated. The ensem bles of free-standing microwires (metallic replicas of the pores obtained after removing of the polymer matrix) were used as the substrates (for deposition of the probe) for ion emission in the mass-spectrometer.It was shown that the intensity of formed ion beam increases with increasing of power of the laser pulse and with increasing of the mass of the probe. The intensity of mass-spectra signal on the power of la ser pulse has a threshold character with saturation accompanied with the appearance of dimer ions.
