<br>
It all depends what you want to do. Wien2k is optimal for
calculating properties of periodic structures, so it is mostly
recommended for bulk.<br>
<br>
For confinement effects aperiodic code is recommended. However it
is unlikely you will ever be able to calculate optical properties
of anything larger than a small cluster aperiodically
(extrapolation is of course a useful tool).<br>
<br>
I myself do use periodic DFT to estimate surface adsorption on
colloidal quantum dots, so you'll have to pick the right tool for
whatever you are interested in.<br>

<div>Dear Wien2k Community,</div>
<div>I am a new user of Wien2k code. I want to know if it is
possible to do simulation study of quantum dots using Wien2k.
Actually, I am about to start a research on quantum dots based
materials for intermediate band solar cells. Therefore, I
really need to know the potential of Wien2k package. Could you
please help me?</div>
<div>With kind regards</div>
