Dielectric constants ofA^IB^IIIC₂^VIandA^IIB^IVC₂^Vchalcopyrite semiconductors

Abstract

A striking correlation has been found to exist between the ionic charge and dielectric constants of A I B III C VI 2 and A II B IV C V 2 chalcopyrite semiconductors. The dielectric constants of these compounds exhibit a linear relationship when plotted on a log-log scale against the nearest neighbour distance d (Å), but fall on different straight lines according to the product of ionic charges of the compounds. A fairly good agreement has been found between the observed and calculated values of the dielectric constants for A I B III C VI 2 and A II B IV C V 2 semiconductors.

Correlation between ionic charge and the optical properties of zinc blende and complex crystal structured solids

“…A detailed study for ionic charges of chalcopyrite has been presented in previous works [16,18]. It is obvious that the valence structures of the compounds can be written as A + B 3+ C 2 2-(A = Cu, Ag; B = Al, Ga, In; C = S, Se, Te) and A 2+ B…”

“…(9) is that the refractive index is related to the high frequency dielectric constant of the crystals [24,25]. The dielectric constant also depends on the product of ionic charges [18]. Thus, there must be a correlation between refractive index and product of ionic charges.…”

Lattice constant of orthorhomic perovskite solids

“…Recently, the authors [15][16][17][18][19] have been evaluated the electronic, mechanical and optical properties of binary and complex crystals with the help of ionic charge theory of solids. This is due to the fact that the ionic charge depends on the number of …”

Lattice energy of zinc blende (AIIIBV and AIIBVI) solids

“…The present authors [7][8][9][10] have recently calculated the electronic, mechanical and optical properties with the help of the ionic charge theory of solids. This is due to the fact that the ionic charge depends on the number of valence electrons, which changes when a metal forms a compound.…”
