Experiments and Calculation of the Al‐Ga‐Sb Ternary Phase Diagram

“…Figure 3 shows the solid solubility of A1 into ternary alloys in equilibrium with ternary liquids containing XSb 1 --~ 0.20 and XA11 = 0.025, 0.05, and 0.10. Our data are in good agreement with those of other authors (5)(6)(7).…”

“…Figure 2 shows the liquidus curves at constant sections of mA] 1 = 0.025-0.20, where xi 1 indicates the atomic fraction of an element i in the liquid. The data reported by other authors (5,6,8) are consistent with the present work.…”

“…) ASF/A2 [5] where ~(xz) = 1 + (R/2,ASF)ln(1/4xlx2), and T F is the melting point and AS ~ is the entropy of fusion of the compound. The values of I~ calculated from the phase diagrams of A1-Sb ( 13) and Ga-Sb ( 14) systems are shown in Fig.…”

“…vide accurate phase boundary because of the limited number of specimens investigated. Several authors (5)(6)(7)(8) also reported the Ga-rich corner of the ternary phase diagram which supplied sufficient information required for the growth of lattice matched ternary layers on GaSb substrates. All of their liquidus and solidus data were experimentally determined below 60O~ The absence of phase separation in the GaSb-A1Sb quasi-binary phase diagram was reported by several authors (9)(10)(11).…”

“…Higgins et at. (5) pointed out the correlation between Ga vacancy-donor complex and so-called surface dead layer. The authors also reported on a capless anneal of ion-implanted GaAs in controlled arsenic vapor (6).…”
