摘要

在第2412750篇文章中，Zakaria Y. Al Balushi及其同事展示了一种选择性区域策略，用于在单层石墨烯中空间调节功函数和载流子密度。通过在类金刚石碳中植入镓离子，并在石墨烯下诱导亚单层镓沉淀，实现了重氮型掺杂。这种方法实现了精确的静电调制，为工程化的2D异质结构和先进的器件架构铺平了道路。

Electrostatic Doping

In article number 2412750, Zakaria Y. Al Balushi and co-workers demonstrate a selective-area strategy for spatially tuning work function and carrier density in monolayer graphene. By implanting gallium ions into diamond-like carbon and inducing sub-monolayer gallium precipitation beneath graphene, heavy n-type doping is achieved. This approach enables precise electrostatic modulation, paving the way for engineered 2D heterostructures and advanced device architectures.
