“…The addition of 5 atyo palladium does not shift the position of this peak in our alloy markedly (less than 0.1 eV). This confirms, similarly to the case of Cu-Zn-Ni alloys [7,111, that small amounts of transition elements do not shift noticeably the Fermi energy level in Cu-Zn alloys with a given copper to zinc atom ratio. This ratio is 4.0 for the Cu-Zn alloy without palladium and 3.75 for the alloy with 5 at% palladium.…”

The optical absorptivity A of Cuo.s-zZno.2Pd, alloys (0 5 z 5 0.2) was measured as a function of the wavelength between 250 nm < 1 < 800 nm a t room temperature in a vacuum system with < Torr. A has a peak (or shoulder) close to 380 nm for x = 0.1.The alloy with z = 0.2 has a minimum at this wavelength. It is proposed that palladium impurities are responsible for virtual energy states which lead to an increase in A below 300 nm and abovc 500 nm. Additionally palladium in higher concentrations absorbs part of the extra electrons of zinc in the copper-zinc matrix. This leads to the minimum of A in the alloy with 20 atyo palladium.

“…It will be instructive to examine the optical conductivity. In figure 3 [13] showed that the Fermi level shifts to higher energies since the number of electrons per atom increases. This is also reflected in our calculated density of state in figure 3 (top).…”

“…We have also applied our methodology to obtain the optical properties of ternary Cu x Ni y Zn z alloys. Schröder and Mamola [13] measured the absorptivity of this alloy with Ni concentration ∼8-10% and increasing Zn concentrations from 10 to 26%. Figure 2 shows their results for percentage absorptivity as a function of wavelength in the top panel and our theoretical results at the bottom.…”

The augmented space approach to the study of random ternary alloys, described in an earlier paper (Alam and Mookerjee 2009 J. Phys.: Condens. Matter 21 195503), has been combined with the generalized recursion method of Viswanath and Müller (1993 The User Friendly Recursion Method, (Troisieme Cycle de la Physique, en Suisse Romande)) and the tight-binding linear muffin-tin orbitals technique (TB-LMTO) to study the optical response in disordered CuxNiyZnz alloys, and compared with existing experimental results.
