Is unique the advantage of interferometric techniques based in speckle phenomena. A Hole field measurement in mechanical elements can be obtained with height precision when they are under deformation. However, when divergent illumination is used, we can s... see more

In this work we obtain the electronic states for a semiconductor quantum cylindrical shell in the matrix GaAs Al Ga As 0.35 0.65 . We have assumed that the system has only one band which splits into a sub-bands system due to confinement. We use the formal... see more
