Flexible and modular virtual scanning probe microscope

摘要: Abstract Non-contact Atomic Force Microscopy (NC-AFM) is an experimental technique capable of imaging almost any surface with atomic resolution, in a wide variety environments. Linking measured images to real understanding system properties often difficult, and many studies combine experiments detailed modelling, particular using virtual simulators directly mimic operation. In this work we present the PyVAFM, flexible modular based force microscope simulating operational mode or set-up. Furthermore, PyVAFM fully expandable allow novel unique set-ups be simulated, finally ships developed documentation tutorial increase usability.

Computer: Desktop. Operating system: UNIX. RAM: 500 Megabytes Classification: 16.4. External routines: GCC, 2.7, scipy numpy Nature problem: Simulation delays/artefacts. Solution method: A simulation was where user can connect several components together order simulate mode. Each these also mathematically similar their life counter parts hence incorporating delays artefacts. Restrictions: For tip-sample interactions beyond simple analytical forms, interaction field should provided by via separate simulations e.g first principles classical calculations. Unusual features: Modularity Additional comments: The tutorials include example approaches fields, authors provide others upon request.
