First-principles investigations of transition-metal nitrides and their alloys with AIN
Abstract
Cutting-edge computational techniques will be used to uncover the prospects of the transition-metal nitrides and their alloys ScAlN and ScTiN. Topics to be addressed include the effects of high doping on the conduction-band structure, polarization moments, roles of defects, scattering mechanisms that limit carrier mobility, and the thermodynamic and electronic properties of various alloys. redictive calculations will lead to a deep understanding of atomic-level mechanisms, provide guidelines to improve the quality of material growth and enable the rich yet unexplored physics exhibited by these materials to be exploited for novel device designs. These results will accelerate the development and adoption of these materials, which will have a strong impact on a wide range of technologies and help enable the next generation of electronic warfare, communications, and radar systems.
