Hafnium is also used as the electrode in plasma cutting because of its ability to shed electrons into air. The high energy content of 178m2 Hf was the concern of a DARPA-funded program in the US. This program determined that the possibility of using a nuclear isomer of hafnium ...
The hafnium atom, with large atomic radius, is surrounded by soft electron clouds and has high chemical activity to attract oxygen ions. It facilitates the accumulation of more oxygen ions around the interface of the top electrode and the resistive switching layer, leading to lower current and Schottky conduction.
hafnium zirconium oxide (HZO) are investigated systematically down to 3 nm. The ferroelectric polarization, switching speed and the impact of atomic layer deposited (ALD) tungsten nitride (WN) electrodes are studied. Record high remnant polarization (P r) on FE HZO and record high saturation polarization (P S) on AFE HZO are achieved with WN
First of all, the hafnium emitter is the single most important part for the electrode. Since hafnium is a poor thermal conductor, it is bonded to the copper body of the electrode using a proprietary process that ensures an excellent thermal and electrical connection.
The results obtained reveal the importance of the top electrode selection to ach … Effects of top electrode material in hafnium-oxide-based memristive systems on highly-doped Si Sci Rep. 2020 Nov 11;10(1):19541. doi: 10.1038/s41598-020-76333-6. Authors Sueda Saylan 1 ...

Use Hafnium wire and Copper to make 9-8215 electrodes——The electrode uses hafnium wire and copper as the main materials. Unlike other products on the market that use cheap Pickaxe wire. the service life of the electrode using hafnium wire is longer than other electrodes using pick wire
Exploring New Metal Electrodes for Ferroelectric Aluminum-Doped Hafnium Oxide Abstract: In this paper, we explore new metal electrodes for ferroelectric capacitors based on Al-doped HfO 2 . We find that Ti/Pd, Ti/Au, and W top electrodes can induce much higher remanent polarization as compared to the traditional TiN top electrode.

Different causes for ferroelectric properties in hafnium oxide were discussed during the last decade including various dopants, stress, electrode materials, and surface energy from different grain sizes. Recently, the focus shifted to the impact of oxygen vacancies on the phase formation process.
Hafnium (atomic symbol: Hf, atomic number: 72) is a Block D, Group 4, Period 6 element with an atomic weight of 178.49. The number of electrons in each of Hafnium's shells is 2, 8, 18, 32, 10, 2 and its electron configuration is [Xe] 4f 14 5d 2 6s 2 .
12%Hafnium (Hf) is used as a refractory cathode material for thermionic emission in a high-temperature region. The consumption of an Hf electrode was investigated by measuring the concavity depth on the Hf electrodes after operations. These measurements were performed under several operating conditions.
