Abstract:
Low-dimensional materials are of booming interest to both experimental as well
as theoretical research [1]. Reduction of one or more spatial dimension(s) to nanometer
range, makes these materials quite di erent in terM.S. of various properties compared
to their bulk counterpart. Fundamentally, quantum con nement e ects are
very prominent in these systeM.S. where the motion of electrons is strongly constrained
along the reduced dimensions. E ect of electron-electron correlation becomes very
much important and quite decisive for the properties of these classes of materials. As
the system-size remains in the range of electron wave length here, understanding the
emerging phenomena in these materials, eventually needs the concept of quantum
mechanics.
