摘要：

We present an analysis, supported by numerical simulations, of the heat and ionization yield for events with incomplete charge collection in low-temperature germanium detectors. A consistent explanation of the ionization and heat balance (including an incomplete Luke effect) at different collection voltages is obtained on the assumption that any carriers (electrons or holes) reaching the surface are trapped at surface states.
