In this study, aluminum nitride (AlN) thin films reactively sputter deposited from an
aluminium target are characterized both under material related aspects as well as on device level for
resonantly driven gyroscopes.
Furthermore, it is a very promising material for the use in optical devices operating in the ultraviolet spectral region [7].
This result can be transferred to the etching performance of materials with a face-centered cubic structure, such as silicon, where the (111) is the etch-stop plane being equivalent to the (002) plane in a hexagonal wurtzite structure [16].
Highly reliable and accurate output signals over the full range of environmental conditions and over its projected lifetime are key requirements for this device which is mainly intended for safety relevant automotive applications.

Abstract.
The start materials were weighed according to the molar ratio of ZnO0.95S0.05 and dissolved in deionized water under stirring for 10 min, and then the compound was transferred to a microwave reactor and heated at 30 ◦C for 2 h.
Locmelis et. al. [20] found that S doped can reduce the band gap of ZnO bulk materials.
In addition, it is well known that the crystalline size of QDs plays key roles in the PL features.
