Electrical characterization of the soft breakdown failure mode in MgO layers [PDF]
, 2009 The soft breakdown (SBD) failure mode in 20 nm thick MgO dielectric layers grown on Si substrates was investigated. We show that during a constant voltage stress, charge trapping and progressive breakdown coexist, and that the degradation dynamics is ...

Time dependent dielectric breakdown and stress induced leakage current characteristics of 8Å EOT HfO2 N-MOSFETS [PDF]
, 2010 In this work we present the time dependent dielectric breakdown (TDDB) characteristics of LaO capped HfO2 layers with an equivalent oxide thickness of 8Å. The layers show maximum operating voltages in excess of 1V. Such high reliability can be attributed

Voltage from mechanical stress in type-II superconductors: Depinning of the magnetic flux by moving dislocations [PDF]
, 2008 Mechanical stress causes motion of defects in solids. We show that in a type-II superconductor a moving dislocation generates a pattern of current that exerts the depinning force on the surrounding vortex lattice.

Lightning Impulse Voltage Stresses In Underground Cables
Journal of Physics: Conference Series, 2023 Abstract Underground power cables are crucial for transmission and distribution. Lightning can stress their insulation, but not directly. So, impulse cable testing is studied. This research examines the cable’s transient response to standard and non-standard lightning impulse voltage waveforms.

On the robustness of ultra-high voltage 4H-SiC IGBTs with an optimized retrograde p-well [PDF]
, 2019 The robustness of ultra-high voltage (>10kV) SiC IGBTs comprising of an optimized retrograde p-well is investigated. Under extensive TCAD simulations, we show that in addition to offering a robust control on threshold voltage and eliminating punch ...
