Removal of GaAs growth substrates from II-VI semiconductor heterostructures

, 2013
We report on a process that enables the removal of II-VI semiconductor epilayers from their GaAs growth substrate and their subsequent transfer to arbitrary host environments.

Preparation of homogeneous sub-micron cerium oxide polishing powder

Jin'gangshi yu moliao moju gongcheng, 2022
To obtain homogeneous submicron cerium dioxide (CeO2) polishing powder, CeO2 was synthesized by solvothermal reaction using cerium nitrate (Ce(NO3)3·6H2O) as cerium resource and alcohol-water mixed solution as solvent.

Individual and interactive action mechanisms of mechanical, chemical, and electrical factors in Co polishing

Friction
With the continuous miniaturization of integrated circuit (IC) devices, Co is recognized as the most promising alternative to Cu as an interconnecting metal. During IC processing, Co surfaces need to be flattened.

Extremely Low Loss Phonon-Trapping Cryogenic Acoustic Cavities for Future Physical Experiments [PDF]

, 2013
Low loss Bulk Acoustic Wave devices are considered from the point of view of the solid state approach as phonon-confining cavities. We demonstrate effective design of such acoustic cavities with phonon-trapping techniques exhibiting extremely high ...

Using Acoustic Emissions for an in-situ evaluation of the polishing process and its parameters [PDF]

EPJ Web of Conferences
Mechanical chemical glass polishing is a complex process with mechanical and chemical interactions. While we have used Acoustic Emissions (AEs) already for basic measurements, we have researched the process and its parameters e.g., the density of the ...

Anomalous optical surface absorption in nominally pure silicon samples at 1550 nm [PDF]

, 2017
The announcement of the direct detection of Gravitational Waves (GW) by the LIGO and Virgo collaboration in February 2016 has removed any uncertainty around the possibility of GW astronomy. It has demonstrated that future detectors with sensitivities ten

Study on the effect of dynamic chemical polishing treatment on porous titanium alloy scaffolds fabricated using laser powder bed fusion

Materials & Design
This study addresses the issue of a significant amount of unmelted powder adhering to the surface of Laser Powder Bed Fusion (LPBF) porous titanium alloy scaffolds, and the current inability of existing technologies to effectively handle such surface ...

Reactive Atom Plasma (RAP) figuring machine for meter class optical surfaces [PDF]

, 2013
A new surface figuring machine called Helios 1200 is presented in this paper. It is designed for the figuring of meter sized optical surfaces with form accuracy correction capability better than 20 nm rms within a reduced number of iterations.
