The classic STM simulation software package designed for STM experimentalists
Nt_STM calculates the electrical current through any given nanometrical system (microscope tip + sample + surface) and reproduces the results of a real STM. It gives current
Nt_STM calculates all interactions between the atoms and provides results accuracy and similarity with the experiments' results.
The simulation engine available today is based on Dr. Jorge Iribas Cerda's "Green" code. More engines are to be added soon.
The nanometrical system is represented by the Extended Hückel Theory (EHT). More precise theoretical chemistry programs can be integrated toNt_STM for specific simulations.
The AFM simulation software package designed for AFM experimentalists
Motivated by the need to aid in the interpretation of experimental Atomic Force Microscopy (AFM) images, this software was developed to self-consistently calculate the
interaction between a tip and surface, and then use this interaction in running a virtual AFM machine that simulates a real experimental device.
The Nt_AFM simulation engine is based on King's College Dr. Lev Kantorovich Sci-Fi and vAFM original codes.
The software can be run in three regimes:
Integrated in a unique interface, Nt_AFM allows for a precise, step-by-step monitoring of the system's (surface+tip+sample) deformations.
