Dear Jatin,

Please follow the following available full-text journal article on Research Gate. Hope this article answers your question even partially. One of our colleagues worked on Quantum dot at KTH Stockholm. If I find something more, will pass to you. Thanks!

Article Recent progress on quantum dot solar cells: A review

There is another open source tool( I don't know if it works, Pls check this)

Dear Jatin,

Some of them are listed below.

a) TiberCAD is a software tool for numerical simulation in the field of electronic and optoelectronic devices.

b) nusod

c) Nextnano for simulation of semiconductor nanodevices

d) Nanohub.org

I used the last one. You can try.

Dear Jatin Chaudhary,

List of few Softwares used for simulation of Quantum Dot.

01. nanoHUB:

Anyone with a nanoHUB username and password can run simulations on nanoHUB. If you do not have a nanoHUB account, you can register online. Registration is quick, easy, and completely free! We use the registration information you provide to report quarterly usage statistics to the National Science Foundation. Installation requirements are minimal: You need to enable Javascript and cookies and have at least Java 1.4 installed.

nanoHUB is operated by the Network for Computational Nanotechnology (NCN), whose mission is to enable the use of modeling and simulation in the advancement of nanoscience and nanotechnology. Most of the tools on nanoHUB are derived from NCN’s contributions to research in the nano areas of electronics, mechanics, bio, photonics, and materials, primarily through leveraged funding.

02. nextnano:

It is powerful tools for the simulation of nanostructures. Applications include nanotransistors, LEDs, laser diodes, quantum dots, nanowires, quantum cascade lasers, HEMTs, infrared detectors and solar cells.

Due to the continuing scaling of semiconductor electronics, quantum physical effects are gaining importance and fundamentally challenge industry with respect to simulation and design.

03. NEMO 3-D:

Enables multi-million atom electronic structure simulations in empirical tight binding; open source; an educational version is on nanoHUB and Quantum Dot Lab. NEMO 3-D calculates eigenstates in (almost) arbitrarily shaped semiconductor structures in the typical column IV and III-V materials. Atoms are represented by the empirical tight binding model using s, sp3s*, or sp3d5s* models with or without spin. Strain is computed using the classical alence force field (VFF) with various Keating-like potentials.

04. Exabyte.io:

Exabyte.io enables computational-, data- and experimental scientists to work together collaboratively, and reliably exploit best-in-class simulation tools, whether commercial, open-source or in-house. Exabyte.io helps streamline and accelerate the research process, and provides the foundation for data analytics and machine intelligence.

05. MAPS:

Materials and Process Simulation, MAPS, platform is a multi-scale, multi-paradigm, extensible platform that allows engineers and scientists to BUILD realistic models of all types of materials, SIMULATE various properties and processes using world-leading simulation engines and ANALYZE for key properties to predict and screen materials behavior under different conditions.

06. tiberCAD:

tiberCAD is a software tool for numerical simulation in the field of electronic and optoelectronic devices. It allows to model and design innovative and nanostructured devices, such as III/V LEDs, nanowire FETs, Dye Solar Cells (DSCs). Both Atomistic and Continuous FEM-based models are available.

07. nusod:

Software Directory available on https://www.nusod.org/inst/soft_nano.html

08. SILVACO TCAD:

3D Process Simulator is a general purpose layout driven 1D, 2D and 3D process simulator including Etching and deposition, Implantation, Diffusion and Oxidation simulation capabilities. Process Simulation Framework. Integrates several process simulation modules in a user-friendly environment provided by Silvaco TCAD interactive tools. General-purpose 3D device simulator using a tetrahedral meshing engine for fast and accurate simulation of complex 3D geometries. Device simulation framework that enables simulation of the electrical, optical, and thermal behavior of semiconductor devices.

09. https://lammps.sandia.gov/ :

LAMMPS is a classical molecular dynamics code with a focus on materials modeling. It's an acronym for Large-scale Atomic/Molecular Massively Parallel Simulator. LAMMPS has potentials for solid-state materials (metals, semiconductors) and soft matter (biomolecules, polymers) and coarse-grained or mesoscopic systems. It can be used to model atoms or, more generically, as a parallel particle simulator at the atomic, meso, or continuum scale. LAMMPS runs on single processors or in parallel using message-passing techniques and a spatial-decomposition of the simulation domain. Many of its models have versions that provide accelerated performance on CPUs, GPUs, and Intel Xeon Phis. The code is designed to be easy to modify or extend with new functionality. LAMMPS is distributed as an open source code under the terms of the GPL. The current version can be downloaded here. Links are also included to older versions. All LAMMPS development is done viaGitHub, so all versions can also be accessed there. Periodic releases are also posted to SourceForge.

I hope the information will help you.

With Best Wishes,

Samir G. Pandya

Thank you for replies.

Rajib Biswas , sir will you please let me know which kind of results were you able to get from nanohub.

I am not able to use this software since a long. I'm trying my best to get access of it.

As far as I know nexnono is paid. You can try Solcore

http://www.solcore.solar/home

comsol multiphysics

I suggest using SILVACO(2D) or (3D) or worst case use the analytical model, in attached you will find an exemple for that :

- Article Modeling and Simulation of GaSb/GaAs Quantum Dot for Solar Cell

- Article Electrical properties of InAsP/Si quantum dot solar cell

good luck
