Abstract

The liquid alloys Ga2Te3, In2Te3, and Tl2Te are well-known examples of liquid semiconductors. More than 20 alloys in these systems, including the stoichiometries listed above, have been studied for photon energies between 0.65 and 3.00 eV. Reflectances lie in the range 25%-65%, relative to a quartz window. The normal reflectances show smooth transitions from behavior characteristic of a small-gap semiconductor to that of a large-gap semiconductor to that of a Drude metal as the compositions are varied from pure Te to pure metal. The data have been fit with oscillator models. The data are consistent with the bonding scheme proposed by Cutler for Tl-Te alloys and a similar model appears to fit the other data as well.
