    I really appreciated the detailed overview of classical and quantum mechanics. I think it helped me understand some of the later material presented on quantum dots. I also appreciate the clear definition of a quantum dot. I am still unsure how modeling an 80nm particle will enable us to engineer atoms, maybe some more information on characterization of quantum dots based on growth technique should be added.

    First off, I would like to say the presentation helped me to understand the nature of quantum dots. it offers an important insight about the true nature of quantum dots as a potential confinement of electrons. The presentation started a bit slow explaining the basics of waves and the dual nature of electrons. I felt that these basic were not necessary for me since i took a number of course about waves. i also took a number of course about quantum mechanics, which also reduced the importance of the explanation about the dual nature of electrons. On the other hand these parts are important as a foundation for people who are unfamiliar with these fields. I enjoyed the perspective of quantum dots as confinements. It was very easy to understand but very hard to explain to others. I would like to thank you for this wonderful presentation

    the presentation was helpful to me…………… however im being honest here and saying my likes and dislikes.

    likes 1. the language and style of the talk was clear and easy 2. the slides and the animations used was brilliant. 3. the application of the quantum dots was told in a fantastic and the most simplistic way i have ever seen. 4. the description and examples of the NEMO-3D was so good that and also the electronics wave functions visualization was unbeleivably great.

    dislikes: 1. the initial part was too long for me and i was waiting when the actual talks regarding quantum dots will start. 2. i expected some detailed information about the growth process or any one of the growth process. also i was wanting that there will be some animation regarding these so in order to make the visualization easy. 3. finally as the name of the presentaion was quantum dot i thought i would see the detailed E-K diagrams, density of states diagram also the 3D animations differentiating DOT, WELL, WIRE and the confinements.so i guess the name should have been modeling or simulating quantum dots or something like that.


    overall though i was looking for detailed info on quantum dots but i got something else which was absolutely facinating for me. i would like to give 9.5 out of 10.

    Finally, I can grasp the visual image of Qdots with the visualisation of the simulation result.

    This was a pretty fascinating presentation. Quantum mechanics and its effects on nanoscale systems is a huge research interest for me, so I was glad to find a presentation that not only discusses particle-wave duality and nanostructures but also gives a lengthy discussion on very real, current research in quantum mechanics. The section on quantum dots seemed short, but the research section supplements it nicely. The subject matter is complex, but the presenter’s light-hearted attitude (the pain pointer, “Quantum WHAT?â€?, etc.) makes it all go down smooth and makes the viewer both not feel bad for falling behind and feel encouraged to go back and try to understand.

    Usually I try to be critical when I write these comments, but I have nothing to add or complain about – a fascinating topic strongly backed up by clear slides and audio delivered by a speaker who is clearly comfortable with and knowledgeable in the subject matter. I hope to find more information on NEMO as I explore more of the Nanohub website – it sounds like a very promising program.

    A rather easy to understand review of history of quantum theory, and q dots. I finally understood what baffled me in undergrad years almost 24 years ago.

    Thank you.
