Stress Analysis of Tungsten Deposition in a 3D Trench Mold With Regard to Initial Nuclei Shape

IEEE Access, 2022
Tungsten has been commonly used for fine interconnects due to its good gap-filling characteristics in 3D molds, such as trench patterns. However, tungsten shows high deposition stress. This causes mold distortion because tungsten has low ad-atom mobility,

Large remnant polarization and great reliability characteristics in W/HZO/W ferroelectric capacitors

Frontiers in Materials, 2022
In this work, the effect of rapid thermal annealing (RTA) temperature on the ferroelectric polarization in zirconium-doped hafnium oxide (HZO) was studied. To maximize remnant polarization (2Pr), in-plane tensile stress was induced by tungsten electrodes

Transition from tunneling to direct contact in tungsten nanojunctions [PDF]

, 2003
We apply the mechanically controllable break junctions technique to investigate the transition from tunneling to direct contact in tungsten. This transition is quite different from that of other metals and is determined by the local electronic properties

Recent advances of nickel hydroxide-based cocatalysts in heterogeneous photocatalysis

Catalysis Communications, 2022
Earth-abundant nickel hydroxide (Ni(OH)2)-based cocatalysts, by virtue of its bargain price, simple synthesis and diverse structure, have attracted increasing research interest in the field of solar-to-fuels conversion.

CCVD synthesis of carbon nanotubes with W/Co–MgO catalysts. [PDF]

, 2008
Carbon nanotubes (CNT) were synthesized from a H2–CH4 mixture with W/Co–MgO catalyst by a catalytic chemical vapour deposition (CCVD) method. Different W/Co ratios were investigated.

X‐Ray Computed Tomography Quantifies Primary Phases and Reveals Crack Morphology in High‐Cycle Fatigue of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.
