Given that existing high-end CCD sensors already have sensitivity to individual photons, I very much doubt that this new graphene sensor can beat that technology by three orders of magnitude. I don't think the laws of physics will allow for three orders of magnitude more improvement in this area.
- mtrimpe 13y agoAre we seriously there already? We really are living in amazing times. Do you happen to have a link to some sources about this?
- Bud 13y agoSure, here are a few: http://www.princetoninstruments.com/cms/index.php/news/8-top-stories/222-emiccd http://www.princetoninstruments.com/cms/index.php/news/8-top... http://iopscience.iop.org/0953-4075/42/11/114011 http://iopscience.iop.org/0953-4075/42/11/114011 http://www.andor.com/learning-academy/astronomy-an-overview-of-andors-solutions-for-astronomy http://www.andor.com/learning-academy/astronomy-an-overview-...
- eru 13y agoYour eyes can actually be sensitive to single photons, if you accustom them to the dark. (It should work better for higher energy photons, i.e. blue light, than lower energy ones.)
