Dense lying self-organized GaAsSb quantum dots on GaAs for efficient lasers [PDF]
Beilstein Journal of Nanotechnology, 2011 GaAsSb quantum dots (QDs) were grown on GaAs in the Stranski–Krastanov (SK) epitaxial mode. Their characteristics were dependent on the Sb/Ga (V/III) flux ratio and the growth temperature. The samples were grown with a V/III ratio between 0.45/1 and 1.50/

Advanced Diamond Microfabrication for Microoptics and Photonics
, 2019 Diamond is an exceptional material - hard, stiff, transparent, which makes it ideal for the fabrication of optical and mechanical systems that take advantage of these properties. Diamond is not only "better", but it offers the possibility of integrating bright colour centres. These optically active defects can be exploited for a variety of applications,

Fabricating Microstructures on Freeform Surfaces via Flexible Hydrogel Micromolds. [PDF]
SmallMicrostructures on flat hydrogel are created by selective illumination. These microstructured gels can adapt to various curved surfaces owing to their softness and flexibility. PDMS replication creates the final array of microstructures. This strategy alleviates the need for sophisticated equipment and complex procedures to fabricate microstructures on
