Latest Nitrides Stories
Gallium nitride (GaN) material holds promise for emerging high-power devices that are more energy efficient than existing technologies "“ but these GaN devices traditionally break down when exposed to high voltages. Now researchers at North Carolina State University have solved the problem, introducing a buffer that allows the GaN devices to handle 10 times greater power."For future renewable technologies, such as the smart grid or electric cars, we need high-power semiconductor devices,"...
CATANIA, Italy, Oct. 29 /PRNewswire/ -- The partners in a new publicly-funded European research project today announced details of the multinational/multidisciplinary program called LAST POWER ('Large Area silicon carbide Substrates and heTeroepitaxial GaN for POWER device applications). The aim of this important 42-month ENIAC (European Nanoelectronics Initiative Advisory Council) project is to provide Europe with strategic independence in the field of wide band gap (WBG) semiconductors....

Open the door to quantum optoelectronic effects in the GaN-based systemFor the very first time, a team of researchers in Germany has introduced quantum dots in fully epitaxial nitride laser structures without the need for hybrid systems -- effectively eliminating the cumbersome method of combining different materials from epitaxy and evaporation. This should help pave the way to a further optimization of lasers and single photon emitters in the visible spectrum region, according to the team....
