Abstract

---

Since the sixties of the past century it is known that energetic (with tens of MeV or more) heavy (with atomic masses being usually larger than that of Ar) ion irradiation (“swift heavy ions”) introduces narrow (~ some nm) but long (typically 10- 100 μm) parallel trails of damage in irradiated polymer foils, the so-called latent ion tracks. The created intrinsic free volume enables electrolytes to penetrate into the polymer, thus forming parallel liquid nanowires. The ion track technology is, in particular, directed towards biosensing applications. The presently developed ion track-based nanosensors (TBNS) provide high sensitivity, low power and low cost. The creation of TBNS requires a careful study of 1) the mechanisms of ion tracks formation, depending on the ion beam parameters and film materials; 2) the regularities of passing the electrolyte through the tracks, depending on their geometry and properties of internal surfaces; 3) the mechanisms of electric response in TBNS. In this presentation it is shown how through the use of improved methods of molecular dynamics, computer aided materials design and computer graphics a number of important problems linked to creating new nanoelectronic devices have been resolved.
