We present here a hybrid approach to modeling helium-ion lithography that combines the power and ease-of-use of the Stopping and Range of Ions in Matter (SRIM) software with the results of recent work simulating secondary electron (SE) yield in helium-ion microscopy. This approach traces along SRIM-produced helium-ion trajectories, generating and simulating trajectories for SEs using a Monte Ca...

The resolution of far-field optical imaging is required to improve beyond the Abbe limit to the subdiffraction or even the nanoscale. In this work, inspired by scanning electronic microscopy (SEM) imaging, in which carbon (or Au) thin films are usually required to be coated on the sample surface before imaging to remove the charging effect while imaging by electrons. We propose a saturation-abs...

SRIM-like codes have limitations in describing general 3D geometries, for modeling radiation displacements and damage in nanostructured materials. A universal, computationally efficient and massively parallel 3D Monte Carlo code, IM3D, has been developed with excellent parallel scaling performance. IM3D is based on fast indexing of scattering integrals and the SRIM stopping power database, and ...

The manuscript reports a study of Kr ion implantation in a Zn target in the 10-50 keV energy range at different source parameters, which combines experimental data and simulation with the SRIM package. The implanted thickness for the 45 keV was found to be 10 μm. The ion penetration depths for different films at different energies (10-50 keV) were calculated using SRIM computer program and foun...

Abstract We present comparisons of the CRANGE code to other well-known codes, SRIM and ASTAR, and to experimental results for ion-material interactions such as energy loss per unit length, ion range, and ion induced electron yield. These ion-material interaction simulations are relevant to the electron cloud effect in heavy ions accelerators for fusion energy and high energy density physics. Pr...

To get an accurate description of has-dynamic motions at the target irradiation with an ion beam we must know the profile of energy release during ion stopping. The experimental dependence dE/dx in graphite with different densities, obtained during the experiments at the SIS-18 (GSI) accelerator by the team of VNIIEF, ITEP and GSI specialists, is presented in Fig.1 [1]. The experimental depende...
