Electron Doping of Ultrathin Black Phosphorus with Cu Adatoms
Steven P. Koenig,Rostislav A. Doganov,Leandro Seixas,Alexandra Carvalho,Jun You Tan,Kenji Watanabe,Takashi Taniguchi,Nikolai Yakovlev,Antonio H. Castro Neto,Barbaros Özyilmaz +9 more
TL;DR: It is found that the addition of Cu adatoms can be used to controllably n-dope few layer black phosphorus, thereby lowering the threshold voltage for n-type conduction without degrading the transport properties.

Physical and electrical characterization of HfO2 metal-insulator-metal capacitors for si analog circuit applications
Hang Hu,Chunxiang Zhu,Yongfeng Lu,Yihong Wu,Thomas Liew,Ming-Fu Li,Byung Jin Cho,Wee Kiong Choi,Nikolai Yakovlev,Nikolai Yakovlev +9 more
TL;DR: In this article, the optical properties of the HfO2 thin films have strong dependence on both the deposition temperature and pressure, while deposition pressure plays an important role in determining the ratio of Hf and O. The electrical properties of metal-insulator-metal (MIM) capacitors were investigated at various deposition temperatures.

Degradation and failure of organic light-emitting devices
TL;DR: In this paper, the degradation and failure of an organic light-emitting device are observed via optical microscopy and the degradation area is identified to be made up of three regions: (1) a dark spot at the center, (2) a nonemitting area forming the core and (3) a weakly emitting area surrounding the core.

Role of gallium diffusion in the formation of a magnetically dead layer at the Y 3 Fe 5 O 12 /Gd 3 Ga 5 O 12 epitaxial interface
Sergey M. Suturin,A. M. Korovin,V. E. Bursian,L. V. Lutsev,V. Bourobina,Nikolai Yakovlev,M. Montecchi,Luca Pasquali,Luca Pasquali,V. Ukleev,A. Vorobiev,A. Devishvili,N. S. Sokolov +12 more
TL;DR: In this article, the origin of a magnetically dead interface layer formed in yttrium iron garnet (YIG) films grown at above 700 C onto a gadolinium gallium garnet substrate by means of laser molecular beam epitaxy is clarified.
