Abstract:
An interface is a common boundary or layer that separates two condensed phases, exists
usually in molecular dimension, composed of chemical compounds from the two surrounding
phases. It has a great effect in determining materials physical and chemical properties, such as
carrier dynamics,1,2 electrics,1 magnetism3,4 etc. Various physical properties of materials in
technological applications are determined by interfaces.5-7 All these properties can be tuned by
engineering the interface of heterostructure materials. A comprehensive understanding and
optimization of the microstructure of the interface and precise control over it provides
opportunities to develop technical advances in device architectures. With the advances of
experimental and theoretical sciences, interface study and engineering have turned out to be
one of the most interesting branch of material research.6,8 The ability of designing engineered
interfaces and obtaining desired properties in heterostructure materials have become an
indispensable goal in material science.
