Thermal conductivity enhancement of aluminum scandium nitride grown by molecular beam epitaxy

open access: yesMaterials Research Letters, 2023
Aluminum scandium nitride (AlScN) has been receiving increasing interest for radio frequency microelectromechanical systems because of their higher achievable bandwidths owing to the larger piezoelectric response of AlScN compared to AlN.

Optimization of Processing Parameters and Adhesive Properties of Aluminum Oxide Thin-Film Transition Layer for Aluminum Substrate Thin-Film Sensor

open access: yesMicromachines, 2022
A thin-film strain micro-sensor is a cutting force sensor that can be integrated with tools. Its elastic substrate is an important intermediate to transfer the strain generated by the tools during cutting to the resistance-grid-sensitive layer.

The influence of heterogenous porosity on silicon nitride/steel wear in lubricated rolling contact [PDF]

open access: yes, 2000
Heterogeneous porosity is detected on the surface and subsurface of hot isostatically pressed (HIPed) silicon nitride spherical rolling elements. The extent of the localised porosity accounts for an area of 6% of the rolling element surface and 4% of the

Joining aluminum directly to aluminum nitride ceramics by a continuous-casting-bonding method

open access: yes, 2003
A new continuous-casting-bonding method is adopted in the work to join aluminum on to aluminum nitride ceramic plates directly. The bonding strength of the directly bonded aluminum/ceramic plate was measured and the interface of the plate was analyzed by
