Molecular beam homoepitaxy of N-polar AlN: enabling role of Al-assisted surface cleaning

Zexuan Zhang, Yusuke Hayashi, Tetsuya Tohei +7

N-polar aluminum nitride (AlN) is an important building block for next-generation high-power RF electronics. We report successful homoepitaxial growth of N-polar AlN by molecular b…

Second Homologous Series of Iron Pnictide Oxide Superconductors (Fe2As2)(Can+2(Al,Ti)nOy)[n = 2,3,4]

Hiraku Ogino, Kenji Machida, Akiyasu Yamamoto +4

We have discovered a new homologous series of iron pnictide oxides (Fe2As2)(Can+2(Al,Ti)nOy)[n = 2,3,4]. These compounds have perovskite-like blocking layers between Fe2As2 layers.…
