Low-Frequency Noise Behavior of AlGaN/GaN HEMTs with Different Al Compositions

Crystals, 2020
AlxGa1−xN/GaN heterostructures with two kinds of Al composition were grown by metal organic chemical vapor deposition (MOCVD) on sapphire substrates. The Al compositions in the AlGaN barrier layer were confirmed to be 13% and 28% using high resolution X ...

Novel materials to enhance keratoprosthesis integration [PDF]

British Journal of Ophthalmology, 2000
The successful integration of keratoprostheses (KPros) within the cornea depends in part on peripheral host keratocyte adhesion to anchor the implant in place and prevent epithelial downgrowth. The following study incorporated different acrylate co-monomers with poly(hydroxyethyl methacrylate) (p(HEMA)) and measured the suitability of these materials ...
