The carrier concentration and conductivity in p-type monovalent copper semiconductors can be significantly enhanced by adding alkali metal impurities. Doping with isovalent and larger-sized alkali ...

Substitutional doping from foreign elements stands out as a preferred method for precisely tailoring the electronic band structure, conduction type, and carrier concentration of pristine materials. In ...

Schematics illustrating the mechanism of the newly developed chemical doping technique and a graph showing how changes in the pH of a solution can be used to control the doping levels of organic ...

Many modern electronic devices we use daily owe their existence to the process of semiconductor doping. Doped semiconductors are the result of careful modifications ...

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 ...

Doping in semiconductors is adding a small amount of impurities into a very pure semiconductor material. It might sound strange to add impurities on purpose, but this is a critical to make ...

Conjugated polymers are the subject of intensive research and development, as they promise large area fabrication of semiconductor devices via low-temperature solution processing. With regard to ...

Semiconductors, often known as computer microchips or integrated circuits (ICs), are an integral part of digital equipment from computers to household appliances to diagnostic instruments and military ...

Perovskite solar cells have been the subject of much research as the next generation of photovoltaic devices. However, many challenges remain to be overcome for the practical application. One of them ...

(Nanowerk News) The carrier concentration and conductivity in p-type monovalent copper semiconductors can be significantly enhanced by adding alkali metal impurities, as shown recently by Tokyo Tech ...
