The most fundamental response of a solid to a plasma and vice versa is electric. An electric double layer forms with a solid-bound electron-rich region-the wall charge-and a plasma-bound electron-depleted region-the plasma sheath. But it is only the plasma sheath which has been studied extensively ever since the beginning of plasma physics. The wall charge received much less attention. Especially little is known about the in-operando electronic structure of plasma-facing solids and how it…

Linkage of electron emission and breakdown mechanism theories from quantum scales to Paschen's law
Numerous applications such as micro- and nanoelectromechanical systems, microplasmas, and directed energy increasingly drive device miniaturization to nanoscale and from vacuum to atmospheric
Invariant embedding approach to secondary electron emission from metals
Based on an invariant embedding principle for the backscattering function, we calculate the electron emission yield for metal surfaces at very low electron impact energies. Solving the embedding
Infrared spectroscopy of surface charges in plasma-facing dielectrics.
Calculating the optical response perturbatively in first order from the Boltzmann equation for the electron-hole plasma inside the solid, it is shown that in the parameter range of interest a classical Drude term results.


Towards an integrated modeling of the plasma-solid interface
Solids facing a plasma are a common situation in many astrophysical systems and laboratory setups. Moreover, many plasma technology applications rely on the control of the plasma-surface interaction,
Kinetic modeling of the electronic response of a dielectric plasma-facing solid
We present a self-consistent kinetic theory for the electronic response of a plasma-facing dielectric solid. Based on the Poisson equation and two sets of spatially separated Boltzmann equations, one
Electron surface layer at the interface of a plasma and a dielectric wall
We study the potential and the charge distribution across the interface of a plasma and a dielectric wall. For this purpose, the charge bound to the wall is modelled as a quasi-stationary electron
Sheaths in laboratory and space plasmas
The sheaths that occur at surfaces in laboratory and space plasmas are reviewed with an emphasis on numerical models that can be solved with modest computational resources. The surfaces in plasma may
Kinetic theory of plasma sheaths surrounding electron-emitting surfaces.
A one-dimensional kinetic theory of sheaths surrounding planar, electron-emitting surfaces is presented which accounts for plasma electrons lost to the surface and the temperature of the emitted
Electron energy loss spectroscopy of wall charges in plasma-facing dielectrics
We propose a setup enabling electron energy loss spectroscopy to determine the density of the electrons accumulated by an electro-positive dielectric in contact with a plasma. It is based on a
Effects of low reflection on the collector and source sheaths of a finite ion temperature plasma
The region between a Maxwellian plasma source and an absorbing surface is described theoretically with a static, kinetic plasma–sheath model and modeled numerically with a dynamic, electrostatic
Plasma Science and Technology in the Limit of the Small: Microcavity Plasmas and Emerging Applications
Over approximately the past decade, a subfield of plasma science has arisen that is redefining frontiers in the physics of low temperature plasma and its applications. Concerned with the confinement
Auger electron spectroscopy of surfaces during exposure to gaseous discharges
The authors report for the first time Auger electron spectroscopy (AES) of a surface while it is exposed to a high pressure, reactive environment: a 5mTorr inductively coupled plasma. An anodized
Kinetic analysis of the collisional plasma?sheath transition
The subdivision of the plasma boundary layer into a quasi-neutral presheath and a collision-free sheath is strictly valid only in the asymptotic limit λD/λ → 0, where λD is the electron Debye length
