r plane sapphire
R-faceted sapphire, or R-Plane sapphire wafers, are a preferred material for heterogeneous epitaxial deposition of silicon in microelectronic IC applications.
With unique physical and optical properties that allow it to exhibit significant advantages in semiconductor, microelectronic, and optical applications, R-faceted sapphire also has unique advantages in specific applications due to its non-polar nature.
r plane sapphire
The R-plane is the non-polar surface of sapphire, a property that allows changes in the position of the R-plane in a sapphire device to result in different mechanical, thermal, electrical and optical properties.
It can also be used in high-end optical devices such as UV spectrometers, infrared detectors, laser systems, etc. The optical transparency and mechanical strength of R-plane sapphire make it an ideal choice for manufacturing high-performance optical windows and lenses.
