Melting point behavior of low dimensional systems

In this paper an attempt has been made to give a detailed review of the melting
point characteristics of materials and their variatio from bulk to nano regime. A proper
understanding of this property is important both from science and engineering aspects.
Main focus has been given on the superheating phenomena which means rise in melting
temperature of a material and how this can be achieved. Both the theoretical developments
done so far supported by enough experimental evidence have been presented in this
work in a chronological manner. Important models such as Surface Area Difference
model (SAD), Liquid Drop Model (LDM) have been discussed in detail and the role of
cohesive energy and surface energy in determining the melting behavior of nano-systems
has been emphasized.
