  Dr. Amar's group is interested in thin film modeling which mostly concerns with Molecular Beam Epitaxy (MBE). MBE is of great technological and practical interest due to the use of MBE to make semiconductors, quantum wells, solid-state lasers, as well as a variety of other nanostructures such as quantum wires and quantum dots. One of the main advantages of MBE is the ability to control the deposition of thin films and atomic structures on the atomic scale in order to create nanostructures. Recently, it has been discovered that even in the absence of effects such as strain, homoepitaxial growth of thin-films may lead to instability known as 'mound formatoin'. This may be due to diffusion bias which may be due to several effects. His group's main topic is to work on the reason behind mound formations and thin film modeling.
