等离子体-固体界面的电子微观物理

Electron microphysics at plasma-solid interfaces

F. X. Bronold, K. Rasek, H. Fehske

摘要:

固体对等离子体和等离子体对固体的最基本的反应是电的。双电层由固体束缚的富电子区(壁电荷)和等离子体束缚的贫电子区(等离子体鞘层)组成。但自从等离子体物理产生以来,人们一直只对等离子体鞘层进行了广泛的研究。城墙上的炸药受到的关注要少得多。特别是鲜为人知的是,在operando面向等离子体的固体的电子结构,以及它如何影响壁电荷的时空尺度。这种观点的目的是鼓励通过现代表面物理学的技术来调查这片隐姓埋名的土地。利用我们自己对等离子体-固体界面电子微观物理的理论探索和通过红外反射率测量壁电荷的建议来进行讨论,我们希望能够为开始这样的努力提供足够令人信服的理由。它们将在等离子体和表面物理学的交叉点上为应用和基础研究开辟一个新的舞台。

英文摘要:

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 affects the spatio-temporal scales of the wall charge. The purpose of this perspective is to encourage investigations of this terra incognito by techniques of modern surface physics. Using our own theoretical explorations of the electron microphysics at plasma-solid interfaces and a proposal for measuring the wall charge by infrared reflectivity to couch the discussion, we hope to put together enough convincing reasons for getting such efforts started. They would open up-at the intersection of plasma and surface physics-a new arena for applied as well as fundamental research.
