6. Linking intermittent plasticity and RF breakdown

Dr Yinon Ashkenazy (The Hebrew University of Jerusalem (IL))

Stochastic models have been proven successful in describing response of systems characterized by intermittent plasticity. We use similar type of models to identify possible mechanisms for RF breakdown. Specifically we explore the option that breakdown is initiated due to a correlated dislocation avalanche, caused by stresses in the sample.

12. Electro-mechanical and thermal simulations of surface under electric field

Dr Vahur Zadin (University of Tartu)

05/11/2013, 15:30

To investigate and understand the interaction between the surface, bulk material and the electric field, we simulated and studied field emitters by analyzing electro-mechanical and thermal effects, possible interactions between the emitters and dynamic field enhancement factor changes due to the mechanical response of the tips using finite element method. To simulate accurately temperature...

Spherical Fe precipitates were simulated with MD in Cu under high electric fields to investigate their effect on dislocations in the Cu lattice. Different depths of the precipitates were studied. Fe precipitates were also placed on Cu grain boundaries.
