Effect of impact ionization in the InGaAs absorber on excess noise of avalanche photodiodes [PDF]
, 2005 The effects of impact ionization in the InGaAs absorption layer on the multiplication, excess noise and breakdown voltage are modeled for avalanche photodiodes (APDs), both with InP and with InAlAs multiplication regions.

Population mechanisms of the green Er3+:LiYF4 laser [PDF]
, 1995 In computer simulations the mechanisms that lead to room-temperature continuous-wave green upconversion lasing in Er3+:LiYF4 are investigated. The rate-equation system considers the full erbium level scheme up to 2H9/2, ground-state depletion, excited ...

Influence of massive material injection on avalanche runaway generation during tokamak disruptions
, 2019 In high-current tokamak devices such as ITER, a runaway avalanche can cause a large amplification of a seed electron population. We show that disruption mitigation by impurity injection may significantly increase the runaway avalanche growth rate in such

Wet-snow avalanche interaction with a deflecting dam: field observations and numerical simulations in a case study [PDF]
Natural Hazards and Earth System Sciences, 2012 In avalanche-prone areas, deflecting dams are widely used to divert avalanches away from endangered objects. In recent years, their effectiveness has been questioned when several large and multiple avalanches have overrun such dams.

Avalanche statistics during coarsening dynamics
, 2019 We study the coarsening dynamics of a two dimensional system via lattice Boltzmann numerical simulations. The system under consideration is a biphasic system consisting of domains of a dispersed phase closely packed together in a continuous phase and ...
