User-friendly software package for simulation and analysis of the atomic scale properties of nanoscale devices. The program provides intuitive and comprehensive tools for gaining insight into the properties of nanoscale devices by simulating measurements through numerical calculations. The workflow within the program is designed to resemble an actual experimental process, and allows the user to set up "virtual experiments" through atomistic modeling. A variety of instruments make it possible to model the geometry, electronic structure and electrical properties of the nanoscale system in an easy-to-use graphical interface.

ATK is a engine behind the VNL based on first principles electronic structure program capable of modeling electrical properties of nanostructured systems coupled to semi-infinite electrodes. The two electrodes, for instance, could be a nanotube and a metal, and the nanostructure could be the interface region between the two systems. Other typical systems include molecules between metal surfaces and interfaces between materials.

ATK is based on non-equilibrium Green's function (NEGF) techniques, and is capable of treating situations in which the two electrodes have different electrochemical potentials, i.e. in which an external bias voltage is applied across the nanostructure. It can calculate the electrical current, voltage drop across the junction, electron transmission waves, etc.

ATK is also capable of performing conventional electronic structure simulations on isolated and periodic systems. The program is based on very efficient electronic structure methods and is a very accurate and efficient method for geometry optimization.

The only STM simulation software package designed for 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 or topographic mode results as well as I(v) or I(z) curves, just like in your experiment. 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 Hckel Theory (EHT). More precise theoretical chemistry programs can be integrated to Nt_STM for specific simulations.

The only AFM simulation software package designed for experimentalists. It is designed to help you entirely and accurately simulate an AFM (Atomic Force Microscope) experiment (contact and non-contact). Our Nt_AFM simulation engine is based on a molecular mechanics modelization system. Integrated in a unique simulation engine, Nt_AFM allows for a precise, step-by-step monitoring of the system's (surface+tip+sample) deformations..
