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 ...

Semiconductors or integrated circuits are microelectronic devices made mostly of silicon or germanium. These chips, though tiny, comprise thousands of different components that work together to ...

The types of devices being deployed in cars and how they differ in functionality. Why each device type requires a different test technique. Determining the best approach for the specific application.

Semiconductor chips consist of dozens of layers, packing immense computing power into a compact form. They store and retrieve data for signaling and control and are essential in creating central ...

A study revealed that a simple thermal reaction of gallium nitride with metallic magnesium results in the formation of a distinctive superlattice structure. This represents the first time researchers ...

In recent years, the energy consumption in developed countries has been rather wasteful. Nearly two-thirds of the total energy is typically discarded into the environment as "waste heat," which ends ...

A spinel-type sulfide semiconductor that can emit light from violet to orange at room temperature has been developed by researchers at Science Tokyo, overcoming the efficiency limitations of current ...

During standardized chip fabrication, integrate circuit (IC) testing is conducted repeatedly to inspect the chips once they are manufactured. IC testing begins with wafer penetration before etched ...

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 ...
