A phase change material comprising a quaternary GaTeSb material consisting essentially of MA(GaxTeySbz)B, and where M comprises a group IVA element C, Si, Ge, Sn, Pb, a group VA element N, P, As, Sb, Bi, or a group VIA element O, S, Se, Te, Po, having a value A such that the transition temperature is increased relative to the transition temperature in GaxTeySbz, without M, and the difference between the melting temperature and the transition temperature is reduced relative to the difference in GaxTeySbz, without M. |
