“…Later on they have proposed a relation between polarizability and bulk modulus of the above compounds and polarizability has been estimated. Recently Author et al 4 have evaluated bulk modulus from Plasmon energy by proposing a linear relation between them and from estimated value of bulk modulus polarizability has been evaluated. The empirical relation between bulk modulus and Plasmon energy proposed by them as:…”

“…There are different methods of materials prepared for these chalcopyrite's compounds have been suggested. [4][5][6][7][8][9] This structure of chalcopyrite which is obtained from that of zinc blende or sphaerlite by the replacement of cationic sublattice by two different atomic species induces the doubling of the unit cell in a direction, which is conventionally called c and a tetragonal distortion. The parameter /a 2 from its position in the cubic cell, where dA-C and dB-C are the cation -anion distances.…”

A simple empirical relation has been proposed to estimate the bulk modulus (B) of ternary chalcopyrite structure solids of I-II-VI, II-IV-V type from the electronegativies of the constituent atoms and the principal quantum number of atoms of the compounds. The present relation is based on chemical bonding model. The electronegativity and principal quantum number determine the chemical bonding of constituent atoms of compounds. The chemical bonding of compounds is the starting point of the stability of compound which is based on the minimum energy principle. In this study, the ground state property like bulk modulus has been correlated with the nature of bonding of materials. The combination of electronegativity and principal quantum number gives a good account of bonding of ternary chalcopyrite structure solids. These two parameters provide a reliable guide to the structural stability of chalcopyrite structure solids. The computed values for bulk modulus are found to be good agreement with the known ones, the comparison between our present values and the ones in the literature is also given.

The analysis of the data is currently, in the statisticians, the object of a true phenomenon of mode, characterized at the same time by the passion and the rejection. To determine the characteristics of a whole of data is obviously not an end in itself, but this lapse of memory is unfortunate because the type of data available always influences the direction of research. The factorial analysis in normalized principal components (PCA), is particularly adapted to the reduction of tables of measurements, where one generally works on a matrix of correlation between characters. In this article we will report our results of analysis into 2 and 3 dimensions of the molecular weight and energy of plasmon of semiconductor chalcopyrites by using what one call the datamining materials. All information was presented in the tables envisaged by an ACP method of the semiconductors étudiés. L' analyzes factorial substitutes for primitive measurements of new variables or factors (which are linear combinations of the primitive variables) with the help of which it is thus possible to optimize the visualization of the data in a restricted number of figures.

“…Thus, it is of great interest to develop a correlation between refractive index and energy gap in solid materials. In recent years, various experimental and theoretical works have been done to generalize the trends in the ionicity (f i) and refractive index (n) of ternary chalcopyrite structures A I B III C2 VI and A II B IV C2 V (Gorai and Mahata, 2010;Neumann, 1987Neumann, , 1985. The empirical relations between different parameters of the crystal, such as unit cell volume, energy gap, ionicity and plasma energy have been given by different researchers.…”
