Abstract

The minimum energy required for the formation of conjugate pair of charged defects is found to be approximately equal to the experimental activation energy for d.c. conductivity in a number of amorphous chalcoganides and pnictides. This observation implies that the defect pair formation energy represents an intrinsic gap for transport in amorphous chalcogenides.

      In addition, at x > 30 at. % As, the mobility of electrons and holes is maximal [24] and, correspondingly, charge diffusion from the SCR increases. This leads to a decrease in the charge density in the SCR and to a decrease in the surface relief upon electron irradiation of these films in comparison with films with a high concentration of Se.

      For example, GeSe2 would have only GeSe bonds, where a Se-rich Ge glass would contain some fraction of SeSe bonds which could be estimated from the stoichiometry. Several lists of bond energies have been used in the past including that of Sanderson [18]. Tg has been shown to correlate well with mean bond energy <E> in covalent glasses, and was shown to relate to the activation energy for viscous flow in an Arrhenius viscosity equation [19].

      These bonds are created in severe sequence decreasing their bond energy awaiting all the valences of the atoms are saturated [42]. We have taken the values of different homo-polar and hetero-polar bond energies from reference [43]. These values are listed in Table 6.

      % can be discussed on the basis of the change in the average bond of the amorphous solid as a function of composition. The single bond energy values [29,30] of Ge–Ge (205.2 k.J·mol− 1), Pb–Pb (85.7 kJ·mol− 1) and Se–Se (206.1 kJ·mol− 1) and Allred–Rochow electronegativity values are used for estimating the single covalent bond energies of Ge–Se (234.9 kJ·mol− 1), Pb–Se (231.2 kJ·mol− 1) etc. Since Te remains constant in Pb–Ge–Se–Te glasses, the variation in average bond energy is only due to the variation of Pb, Ge and Se in these glasses.

      Thus, if only the strength of a Ge–Te bond is weaker than that of Pb–Te bond, the amount of Te ions which are incorporated into will decrease with the increasing of Ge concentration in the films. Our assumption can be supported from the experimental data of bond energies reported by Rao and Mohan [12]. It is pointed out that Ge–Te has energy of 1.87 eV, whereas Pb–Te has 1.90 eV, therefore, Ge ions cannot “hold” Te ions as tight as Pb ions do.
