Hello. I feel as though I should mention (before I say anything else) that this is my first year in grad school (first SEMESTER even). I haven't taken any modern physics lab courses (aside from an undergrad course years ago) that would help me with my research or my question. My PhD research involves the use of quantum dots to create single photons. At this point, I have read a whole bunch of papers and documentation of what quantum dots are, and how they can be used to create single photons. But now it has come time to actually purchase these things and use them as they papers describe. The problem I am having is that there seems to be a "disconnect." Meaning, I don't know what to expect when buying these things, or how I would use them in the lab. I googled "Purchase Quantum Dots." and got this website.. http://www.nn-labs.com/index.php?op...50&Itemid=94&gclid=CLO7q4b0vLoCFUyk4AodG00AAg I don't know why the dots come in those jars, or how I would use that. According to the papers I have been reading, making a single photon emitter involves connecting 4 dots via "tunneling connections" and then exciting one of them. I imagine these things are extremely small and I don't know how I am supposed to deal with them. I am aware that I need to speak to someone in person that deals with these types of experiments, and I will. But I was wondering if I could gain any insight from these forums. Thanks!
