The process of electron-beam-induced deposition (EBID) was simulated with a dynamic Monte Carlo profile simulator, and the growth of carbon, silver, and tungsten supertips was investigated to study the dependence of material composition on the spatial resolution of EBID. Because light atoms have a smaller scattering angle and a longer mean free path, the carbon supertip has the smallest lateral size and the highest aspect ratio of a bottom tip compared to silver and tungsten supertips. Thus the best spatial resolution of EBID can be achieved on materials of low atomic number. The calculation also indicated a significant contribution of primary electrons to the growth of a supertip in EBID, which is consistent with the experimental observations. These results lead to a more comprehensive understanding of EBID, which is a complex interaction process between electrons and solids.

Experimental Findings

The configurational and magnetic properties of magnetic polymers are investigated based on an Ising polymer chain model with nearest-neighbor spin-spin interaction on the simple cubic lattice. Dynamic Monte Carlo simulation shows that the model has spontaneous magnetization at low temperature, i.e. the mean-square magnetization <M2> approaches to 1 below the critical temperature Tc. Near Tc, a transition of chain spatial configuration from extended coil to compacted globule is found. A nonlinear magnetization - field curve is observed, in agreement with experimental findings for magnetic polymers.
