Advancing Threshold-Inception Modeling for Predictive Simulation of Ionic Wind Fan Performance
Siim Heering, Juri Volodin, Vootele Mets +5
This study investigates the predictive capability of a threshold inception-based multiphysics modeling approach for ionic wind fans by direct comparison with experimental measureme…
Coupled simulation of plasma-surface interactions during early stages of vacuum arcing
Roni Koitermaa, Andreas Kyritsakis, Tauno Tiirats +2
We describe fully coupled simulations that bridge atomistic cathode dynamics and plasma formation during the earliest stages of vacuum arcing. The model combines molecular dynamics…
Methods for an Electron Emission Digital Twin
Salvador Barranco Carceles, Veronika Zadin, Steve Wells +3
The effective design and operation of electron emitters is the core of critical technologies such as high-resolution electron imaging and spectroscopy or X-ray production for medic…
Influence of an external static magnetic field on prebreakdown electron emission and heating
Roni Koitermaa, Marzhan Toktaganova, Andreas Kyritsakis +4
High magnetic fields can increase the occurrence of vacuum arcing, suggesting that both electric and magnetic fields can play a role in the vacuum arcing process. The mechanism of…
Towards 4D modelisation of thermal-field emission from semiconductors
Salvador Barranco Cárceles, Aquila Mavalankar, Veronika Zadin +2
The theoretical picture of thermal field-emission (TFE) from semiconductors has been limited to 1D and 2D models. This can be attributed to the complex and interdependent phenomena…
Theory and computation of thermal-field emission from semiconductors
Salvador Barranco Cárceles, Veronika Zadin, Aquila Mavalankar +2
Semiconducting field emitters present some interesting features (e.g.; self-limited electron emission) for both scientific interest and industrial applications. The analysis of exp…
In-situ observation of field-induced nano-protrusion growth on a carbon-coated tungsten nanotip
Guodong Meng, Yimeng Li, Roni Aleksi Koitermaa +3
Nano-protrusion (NP) on metal surface and its inevitable contamination layer under high electric field is often considered as the primary precursor that leads to vacuum breakdown,…
Simulating vacuum arc initiation by coupling emission, heating and plasma processes
Roni Koitermaa, Andreas Kyritsakis, Tauno Tiirats +2
Vacuum arcing poses significant challenges for high-field vacuum devices, underscoring the importance of understanding it for their efficient design. A detailed description of the…
Comparison of the Resistivities of Nanostructured Films Made from Silver, Copper-Silver and Copper Nanoparticle and Nanowire Suspensions
Boris Polyakov, Aleksandrs Novikovs, Madara Leimane +7
Spray deposition and inkjet printing of various nanostructures are emerging complementary methods for creating conductive coatings on different substrates. In comparison to establi…
Nano1D: An accurate Computer Vision software for analysis and segmentation of low-dimensional nanostructures
Ehsan Moradpur-Tari, Sergei Vlassov, Sven Oras +5
Nanoparticles in microscopy images are usually analyzed qualitatively or manually and there is a need for autonomous quantitative analysis of these objects. In this paper, we prese…
Biased self-diffusion on Cu surface due to electric field gradients
Jyri Kimari, Ye Wang, Andreas Kyritsakis +2
Under strong electric fields, an arc of strong current flowing through plasma can link two metal surfaces even in ultra high vacuum. Despite decades of research, the chain of event…
