A study on dynamic avalanche test of IGBT module

open access: yes机车电传动, 2023
During the turn-off of IGBT modules, dynamic avalanche will occur when a large electric field is generated inside the chip. In this paper, an experimental scheme was designed and verified to analyze the effect of different factors on dynamic avalanche ...

Avalanche criticality in the martensitic transition of Cu67.64Zn16.71Al15.65 shape-memory alloy: a calorimetric and acoustic emission study [PDF]

open access: yes, 2010
The first-order diffusionless structural transition in Cu67.64Zn16.71Al15.65 is characterized by jerky propagation of phase fronts related to the appearance of avalanches.

Non-equilibrium hysteresis and spin relaxation in the mixed-anisotropy dipolar coupled spin-glass LiHo$_{0.5}$Er$_{0.5}$F$_{4}$ [PDF]

open access: yes, 2014
We present a study of the model spin-glass LiHo$_{0.5}$Er$_{0.5}$F$_4$ using simultaneous AC susceptibility, magnetization and magnetocaloric effect measurements along with small angle neutron scattering (SANS) at sub-Kelvin temperatures.

Snow variability effect upon avalanching

open access: yesIce and Snow, 2015
Thickness, density, shearing strength, and temperature of snow on mountain slopes are considered as stochastic fields or processes. Parameters of these fields (processes) were estimated in several geographical regions. Errors of snow stability estimation are shown to be depending on the above parameters, quantity of point measurements, and the ...

Effect of impact ionization in the InGaAs absorber on excess noise of avalanche photodiodes [PDF]

open access: yes, 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.
