Dielectric constant boost in amorphous sesquioxides

Pietro Delugas, Vincenzo Fiorentini, Alessio Filippetti

High-kappa dielectrics for insulating layers are a current key ingredient of microelectronics. X2O3 sesquioxide compounds are among the candidates. Here we show for a typical mater…

Conservation of dielectric constant upon amorphization in perovskite oxides

Pietro Delugas, Vincenzo Fiorentini, Alessio Filippetti +1

We report calculations indicating that amorphous RAO $_{3}$ oxides, with R and A trivalent cations, have approximately the same static dielectric constant as their perovskite crystal…

Ab-initio description of hole localization and Zhang-Rice singlets in one-dimensional doped cuprates

Alessio Filippetti, Vincenzo Fiorentini

We present the first ab-initio band-theory-based description of spin-compensated polarons (known as Zhang-Rice singlets) in a hole-doped cuprate, specifically one-dimensional Ca_{2…

Chain metallicity and antiferro-paramagnetism competition in underdoped YBa $_{2}$ Cu $_{3}$ O $_{6 + x}$ : a first principles description

Alessio Filippetti, Giorgia M. Lopez, Mauro Mantega +1

We describe from advanced first principles calculations the energetics of oxygen doping and its relation to insulator-metal transitions in underdoped YBa $_{2}$ Cu $_{3}$ O $_{6 + x}$ . We fin…
