What properties of Germanium make it suitable for Dark Matter detectors? I tried googling but there was too many results describing the use of Germanium Chrystals at low tempretures for Dark Matter detaction but not the why of it.
Or alternatively what are the properties that make a good dark matter detector? in this case Germanium just gets to fit the requirement and have a look at other possible candidates.
Assuming Germanium is rare and hard to get I prompted this question, on the other hand if it was copper that was being used for such a task, it would have gone completely unnoticed.
