Modulation of electron transport during Swing ECCD discharges in TCV

Olivier Sauter, Timothy Goodman, Stefano Alberti, Costanza Zucca

Generation of a swing electron cyclotron current drive (swing ECCD), i.e. driving alternated, symmetric, positive or negative local ECCD, during a single discharge and at constant total input EC power, was performed at the Tokamak a Configuration Variable ...

Combinatorial Chemical Vapor Deposition of Lithium Niobate Thin Films

Patrik Willi Hoffmann, Silviu Cosmin Sandu, Ali Dabirian, Yury Kuzminykh, Estelle Wagner, Giacomo Benvenuti

Combinatorial lithium niobate deposition on 150 mm naturally oxidized silicon (100) wafers in a high-vacuum chemical vapor deposition reactor using Li(OBut) and Nb(OEt)4(dmae) is presented. The novel precursor supply system allows individual spatial contro ...

Electrospray ion beam deposition and mass spectrometry of nonvolatile molecules and nanomaterials

Stephan Rauschenbach

The vacuum deposition of complex functional molecules and nanoparticles by thermal sublimation is often hindered due to their extremely low vapor pressure. This especially impedes the application of ultrahigh vacuum (UHV) based analytical and surface modif ...

Fabrication of 10 nm diameter hydrocarbon nanopores

Aleksandra Radenovic

The addition of carbon to samples, during transmission electron microscope imaging, presents a barrier to accurate analysis; the controlled deposition of hydrocarbons by a focused electron beam can be a useful technique for local nanometer-scale sculpting ...

Irreversible evolution of many-electron systems: From the quantum-Boltzmann equation toward the semi-classical Boltzmann equation

Starting from the quantum-Boltzmann equation derived in a previous paper, we study the irreversible evolution of an electron gas in the one-particle phase space. The connection with phase space is established by expressing one-electron states in terms of t ...

Gas-assisted focused electron beam and ion beam processing and fabrication

Patrik Willi Hoffmann, Ivo Utke

Beams of electrons and ions are now fairly routinely focused to dimensions in the nanometer range. Since the beams can be used to locally alter material at the point where they are incident on a surface, they represent direct nanofabrication tools. The aut ...

Oxygen assisted focused electron beam induced deposition of silicon dioxide

Alexandre Perentes

Focused Electron Beam Induced Deposition (FEBID) is a rapid prototyping technique for the investigation, production and modification of 2 and 3-D nanostructures. The process takes place at room temperature, in the high-vacuum chamber of a Scanning Electron ...

Oxygen assisted focused electron beam induced deposition of Si-containing materials: Growth dynamics

Patrik Willi Hoffmann

The growth dynamics of oxygen assisted focused electron beam induced deposition of Si-containing materials (from SiOxCy to SiO2) were investigated as a function of relevant process parameters. The results obtained from organosilanes of different families ( ...

Effects of chlorine residue in atomic layer deposition hafnium oxide: A density-functional-theory study

Wei Chen, Min Xu

Hafnium tetrachloride is one of the most commonly used precursors for atomic layer deposition of HfO2. According to the experimental result, chlorine residue is almost unavoidably incorporated during the deposition process. We performed first-principles ca ...

ELM transport in the JET scrape-off layer

Richard Pitts, Gilles Arnoux

This contribution summarizes a number of aspects of the experimental and modelling programme at JET aimed at improving the characterization and understanding of edge localized mode (ELM) transport in the scrape-off layer (SOL). Divertor target energy depos ...
