Abstract
Sublimation of alkali halides (NaCl and LiCl) onto a pre-assembled hydrogen-bonded layer of TCNQ on Au(111) resulted in the formation of 2D ionic layers via a direct charge-transfer reaction without involvement of the substrate. The presented approach allows for the fabrication of different ionic layers, decoupled from the substrate and offering new, potentially interesting properties.
摘要
碱金属卤化物（NaCl 和 LiCl）在预先组装的 TCNQ 氢键层上升华到 Au(111)上，通过直接电荷转移反应形成二维离子层，而不涉及衬底。所提出的方法允许制造不同的离子层，与衬底解耦，并提供新的、潜在有趣的性质。
