We present ab initio pseudopotential–density-functional calculations for the electronic structure of the dilute magnetic semiconductor MnxGa1-xP, with a realistic x=0.063, in its ordered ferromagnetic phase. We find that it possesses a spin-polarized valence band that could support ideal spin-polarized hole transport. We further find spin-polarized features in the conduction band that could support ideal spin-polarized transport of minority electrons. As such, it emerges as a silicon-lattice-matched candidate material for spintronics applications.

    Lanthanum and yttrium compounds with composition RE2 M2 O7 (RE = Y, La; M = Ti, Zr, Hf) have high density and high Z and can be doped with Ce onto the La and Y sites. This makes these compounds good candidates for Ce-activated scintillator γ-ray detectors particularly for the hafnate systems...

    Owing to the wide bandgap of silicon carbide, p- n structures based on this semiconductor are characterized by low densities of the generation current. For this reason, it is possible to increase the working temperature of SiC-based p- n detectors of nuclear radiation so as to control the time...
