Plasma surface physics

Charge-transfer across the plasma-wall interface

Plasma surface sheath

Fundamental to any interface is charge transfer. This mantra also holds for the
interface between a plasma and a solid surface. Our research activities in this
field are geared towards a microscopic, quantum-kinetic understanding of charge
transfer across the dielectric in (miniaturized) barrier discharges. Besides
the elementary processes of electron [1] and hole [2] injection into the
dielectric we also study global properties of the electric double layer building
up at any plasma-wall interface [3,4]. The overriding goal thereby is to identify
wall materials/structures opening up novel opto-electronic applications for solids
in contact with a plasma.
