Phasons,topological defects and dynamics in incommensurate matter
In this thesis, we derive some physical consequences of the existence of a phason mode in incommensurate materials. We consider two main examples of such materials-quasicrystals and the incommensurate twist grain boundary ... -
Studies of the vibrational and magnetic properties of layered compounds
In this final and concluding chapter, we summarize the important observations presented in the previous chapters and discuss the scope of future work in the systems under study. The main points dealt with in this thesis ... -
Study of the source-substrate geometry to achieve thickness uniformity of thin films
Despite the various technical skills that are available, the thickness uniformity cannot be made better than ±1% on a large number of substrates. In addition to the theoretical limitations, one has practical difficulties ...
