Design diffusion factor of dm 0.5
Webthe diffusion rate at normal operating temperatures is too slow to have an effect on device performance. However, when large grain boundaries or large numbers of surface defects exist, the diffusion rate can be fast [2]. Au has a high diffusion factor into GaAs, therefore a Pt or Pd layer is employed to act as a barrier to Au diffusion into GaAs. WebThe m-value (“mu-value”) of a material is also known as its “water vapour resistance factor”. It is a measure of the material’s relative reluctance to let water vapour (steam/condensation) pass through, and is measure in comparison to the properties of air. The lower the m-value, the more breathable the material. It is a property of the material itself and independent of …
