Mechanical properties and microstructure of microcrystalline GaN

摘要

The mechanical properties and microstructure of microcrystalline GaN layers have been studied. This compound is shown to have a low defect density, high hardness and rather good plasticity. The specific behaviours of the dependences of microhardness on load and of brittleness on load are explained using the dislocation-disclination deformation mechanism. [References: 9]
