A model based DC analysis of SiPM breakdown voltages
, 2017 A new method to determine the breakdown voltage of SiPMs is presented. It is backed up by a DC model which describes the breakdown phenomenon by distinct avalanche turn-on ($V_{01}$) and turn off ($V_{10}$) voltages.

Analytical description of ballistic spin currents and torques in magnetic tunnel junctions [PDF]
, 2015 In this work we demonstrate explicit analytical expressions for both charge and spin currents which constitute the 2x2 spinor in magnetic tunnel junctions with noncollinear magnetizations under applied voltage. The calculations have been performed within
