Area and volume effects on breakdown strength in liquid nitrogen [PDF]

open access: yes, 1995
We measured dc and ac breakdown voltages in liquid nitrogen (LN_2) with a sphere-to-plane electrode configuration. Experimental results revealed that the breakdown voltage in LN_2 did not increase monotonously but partially decreased as the sphere ...

Buried Unstrained Germanium Channels: A Lattice‐Matched Platform for Quantum Technology

open access: yesAdvanced Science, EarlyView.
ABSTRACT Strained germanium (ε$\varepsilon$‐Ge) and strained silicon (ε$\varepsilon$‐Si) buried quantum wells have enabled advanced spin‐qubit quantum processors. However, in the absence of suitable lattice‐matched substrates, ε$\varepsilon$‐Ge and ε$\varepsilon$‐Si are deposited on defective, metamorphic SiGe buffers, which may impact device ...

Flexible Unusual Ternary‐Component Graded‐Modulus Dielectric Films with High‐Density Capacitive Energy Storage

open access: yesAdvanced Science, EarlyView.
Hierarchical PP–LSR107–BaTiO3 nanocomposite films are fabricated by one‐step extrusion and stretching for roll‐to‐roll manufacture, combining high energy storage and processing flexibility. LSR107 surrounds BaTiO3‐rich regions, locating amorphous PP, decreasing defects, and introducing deep traps that homogenize the electric field and suppress charge ...

Space charge and its impact on DC breakdown of polymeric materials

open access: yes, 2013
The presence of space charge will lead to distortion of electric field distribution within the dielectric material, resulting electric field enhancement in certain region of the dielectric. The electric field enhancement could cause material degradation,

Field‐Free Spin‐Splitting‐Torque Driven Stochastic Neuron Mimicking the Neuromorphic Imagination for High‐Performance Recognition

open access: yesAdvanced Science, EarlyView.
The human brain's imagination, which enables autonomous driving hazard avoidance by completing missing visual information, relies on Gaussian‐stochastic neuron. We report the altermagnetic RuO2 spintronic neurons integrating field‐free switching and intrinsic Gaussian stochasticity, building an all‐spin ANN for high‐quality image repairing and high ...
