About qBaandi

Welcome to qBaandi.

The thematic simulation platform for light emitting quantum dots

KIST’s thematic platforms were built to offer research environment of material simulations, even for experimentalists and students who never learned simulations. This platform provides computing resources and all kinds of software necessary for simulations; atomic structure modeling programs, simulation solvers (DFT, MD, MC and many others), solver GUI and data visualization programs. You don’t need any further software and high performance computers but only need the web browser.
qBaandi was designed for optical and electronic structure analysis for semiconductors, especially for quantum dots.

Enjoy simulations!

Luminescence Lab

Luminescence calculations using effective mass approximation (EMA). PL intensity, wave functions of electrons and holes, optical gaps and switching intensity are available for quantum dots.

Atomistic Modeling Lab

Electronic structure analysis using density funcitonal theory (DFT) calculations. Density of states, spin density, Mulliken charge and optical properties (dielectric functions, absorption intensity and optical conductivity) are available.

Stability Lab

Simulations of quantum dot degradation using reactive force field (ReaxFF) molecular dynamics (MD).


The qBaandi was supported by Nano·Material Technology Development Program through the National Research Foundation of Korea(NRF) funded by the Ministry of Science and ICT. Computational Science Research Center at Korea Institute of Science and Technology (KIST) manages the qBaandi. Contact: contact.vfab@gmail.com
