Dimension Dependent Density-of-States Function and the Radiation Laws.

The concept of dimension dependent density-of-states function (DOS) is vital in the area of nanoscience and nanotechnology. In this paper we show that the same concept leads to the simple and compact derivations of the 3D, 2D and 1D Planck's radiation laws in one hand and its two dimension dependent extremes namely Rayleigh-Jeans and Wien's laws on the other hand. Besides we have also studied the 3D, 2D and 1D Stefan-Boltzmann laws in this context.
