Abstract
In the general system (Cu1−xAgx)(Ga1−yIny)(Se1−zTez)2, samples were prepared for the six sections defined by the valuesx=0, 1,y=0,1 andz=0,1. The polycrystalline samples were prepared by a melt and anneal technique, different annealing temperatures being used depending upon the alloy composition and annealing times of up to 4 months being required to give equilibrium conditions. Debye-Scherrer X-ray powder photographs were used to investigate the equilibrium conditions and it was established that a single-phase chalcopyrite structure was obtained at most compositions in vestigated. Values of lattice parametersa andc were determined and for each section the variations ofa andc with composition were fitted to power series in the appropriate composition coordinates. Hence contours of constanta and of constantc were determined. Values of optical-energy gapE0 were determined by opticalabsorption measurements for alloys in the copper (x=0) and indium (y=1) sections. These values were also fitted to power series and contours of constantE0 determined.

I campioni policristallini sono stati preparati con una tecnica di fusione e tempra, con diverse temperature di tempra in relazione alla composizione della lega e con tempi di tempra lunghi fino a 4 mesi per dare condizioni di equilibrio. Fotografie delle polveri ai raggi X secondo Debye e Scherrer sono state usate per indagare le condizioni di equilibrio e si è stabilito che una struttura di calcopirite a fase singola si è ottenuta per la maggior parte delle composizioni studiate. I valori dei parametri del reticoloa ec sono stati determinati e per ogni sezione le variazioni dia ec con la composizione sono state adattate alle serie di potenza nelle appropriate coordinate di composizione. Sono stati quindi determinati contorni cona costante ec costante. I valori del gap di energia otticaE0 sono stati determinati mediante misurazioni dell'assorbimento ottico per leghe nelle sezioni del rame (x=0) e dell'indio (y=1). Questi valori sono stati poi adattati a serie di potenza e sono stati determinati i contorni conE0 costante.</abstract><abstract lang="und">Р общей системе (Cu1−xAgx)(Ga1−yIny)(Se1−zTez) приготовляются образℙы для шести зон, определенных знчениямиx=0,1,y=0,1 иz=0,1.

Для исследования условий равновесия используются ренттеновские фотографии почoшкор Дебая-Шеррера.
