A South Korean research team has, for the first time, uncovered the molecular-level mechanism by which trace amounts of impurities—known as dopants—can reverse charge polarity in organic polymer ...

For traditional semiconductor materials and devices, controlling the distribution of electrical doping to build an internal electric field is a common method to enhance carrier extraction efficiency, ...

A recent article in Nature Communications introduced a method for precise p- and n-type substitutional doping of two-dimensional (2D) semiconductors. This method was applied for the one-step growth of ...
