Additional information

A new realistic model for X-ray avalanche photodiodes was reported. We showed that conventional understanding of avalanche gain (which amplifies the signals) being accompanied by severely degraded energy resolution are flawed, and that X-ray avalanche photodiodes is more attractive than previously thought. The work has since led to an EPSRC grant (EP/I010920/1, £106k) and is one of 3 themes in another EPSRC grant (EP/K001469/1, £639k). Institute of High Energy Physics, Russia, is collaborating with us to develop X-ray imaging arrays for medical applications.
