Structural, morphological, and optical properties of AlGaN/GaN heterostructures with AlN buffer and interlayer
TL;DR: In this paper, the effects of an AlN buffer layer (BL) grown on an Al2O3 substrate and an ALN interlayer (IL) grown under the AlGaN ternary layer (TL) on structural, morphological, and optical properties of the heterostructures have been investigated by high-resolution x-ray diffraction, spectroscopic ellipsometry, atomic force microscopy, and photoluminescence measurements.

Microcalorimetric measurements of the heat of adsorption of Pb on well-defined oxides: MgO(100) and p(2×1)-oxide on Mo(100)
TL;DR: In this paper, the authors measured the energy of Pb film grown at 300 K on two well-defined oxides [a MgO(100) thin film and a p(2×1)-oxide on Mo(100)] using single-crystal adsorption microcalorimetry.
