Hafnium(IV) oxide is used in optical coatings and in advanced metal-oxide-semiconductor devices. It is used as a gate insulator in field-effect transistors due to its high dielectric constant. It plays an important role as a possible candidate for resistive-switching memories, as a refractory ...
Study of hafnium oxide films as a high dielectric constant material for IC applications: Their deposition and characterization.In view of the physical limit of the thickness of thin SiO;In this work, four magnetron sputtering approaches were used for the deposition of HFO;Parameters such as ...
(Choi et al., 2011; Kita & Toriumi, 2009; Noriyuki Miyata Science Reports, 2018). It is because that it possesses highstatic dielectric constant(~25), significantly high break down the electric field (~8.5MV/cm), wide-band gap energy (~5.6eV) and also exhibits high thermal stability ...
Hafnium Oxide Nanoparticles (HfO2) Applications Hafnium oxide (HfO2) is a kind of wide band gap and high dielectric constant of ceramic materials. Hafnia is used in optical coatings, and as a high-k dielectric in DRAM capacitors, future integrated circuits, as a refractory material…..Hafnium...
The annealed dielectric layer with UV-ozone oxidation attained a high dielectric constant, and no hysteresis was detected in the C–V measurements. Two-dimensional (2D) carbon structure of reduced graphene oxide (rGO) was used for the active channel of the TFTs, because of its superior ...
Hafnium-based compounds are employed in gates of transistors as a insulators in the 45 nm (and below) generation of integrated circuits from Intel, IBM and others.[58][59] Hafnium oxide-based compounds are practical high-k dielectrics, allowing reduction of the gate leakage current which improve...

The dielectric constant is around 16 which is very good, since the surface of the silicon where the HfO2 films were deposited contains a SiO2 layer of about 3 nm that gives an effective dielectric constant above 20, close to the HfO2 stoichiometric value (25). Further increase on the O2...
