The I D current as a function of the V DS voltage for different positions of a single charged block and for different values of the reference electrode have been calculated. The electrostatic behaviour (transfer characteristics) of a general BioFET structure has been simulated when the captured target number increases from 1 to 10.
In particular, the parameters of an intrinsic semiconductor material have been set in order to reproduce an electrolyte solution.īy replacing the electrolyte solution with an intrinsic semiconductor, the electrostatic solution of the electrolyte region can therefore be calculated by solving the semiconductor equation within this region. The properties of a custom-defined material were modified in order to reproduce the electrolyte behavior. In this work we present a numerical simulation approach to the study of ISFET structures for bio-sensing devices (BioFET) using Synopsys Sentaurus Technology Computer-Aided Design (TCAD) tools. Aiming at the optimization of the design and fabrication processes of BioFETs, the correlation between technological parameters and device electrical response can be obtained by means of an electrical device-level simulation.

Users can furthermore extend the capabilities and interfaces of the package by implementing their own plugins in order to, for example, support additional file formats, combine and plot data in different ways, and set up new types of structures.Īt present, QuantumWise has more than 20 employees world-wide, working with developing the code and supporting our users.Ion Sensitive Field Effect Transistors (ISFETs) are one of the primitive structures for the fabrication of biosensors (BioFETs). VNL can operate as a standalone interface to various different codes, with capabilities to build geometries, set up calculations, and read and plot output results produced by FHI-aims, VASP, QuantumEspresso, LAMMPS, and GPAW, among others.

Virtual NanoLab (VNL) works as a graphical user interface for Atomistix ToolKit (ATK), but QuantumWise also develops extendable tools allowing VNL to act as a flexible graphical user interface (GUI) for other software packages apart from ATK. A particular focus is the ability to handle large-scale systems, and the main engine offers unique capabilities to compute tunneling/leakage currents, transistor characteristics and other transport properties.
The software can be used to investigate novel device ideas for semiconductors and nanoelectronics based on molecular junctions, nanotubes, graphene, molecular electronics junctions, nanowires, etc, as well as study properties of complex interfaces, high-k materials, and magneto-tunnel junctions. In addition to developing our own simulation software engine, Atomistix ToolKit (ATK), we also offer customers our services for integrating other software packages (in-house or publicly available) into our platform, and development of customized modules for specific purposes.ĪTK offers a homogeneous interface to many different atomic-scale methods, ranging from first-principles methods to tight-binding and classical potentials. QuantumWise specializes in advanced solutions for atomic-scale modeling of nanostructures, bulk materials, surfaces, and interfaces.
