In proximity to an s-wave superconductor, a one- or two-dimensional,electron- or hole-doped semiconductor with a sizable spin-orbit coupling and aZeeman splitting can support a topological superconducting (TS) state. Thesemiconductor TS state has Majorana fermions as localized zero-energyexcitations at order parameter defects such as vortices and sample edges. Herewe examine the effects of quenched disorder from the semiconductor surface onthe stability of the TS state in both electron- and hole-doped semiconductors.By considering the interplay of broken time reversal symmetry (due to Zeemansplitting) and disorder we derive an expression for the disorder suppression ofthe superconducting quasiparticle gap in the TS state. We conclude that theeffects of disorder can be minimized by increasing the ratio of the spin-orbitenergy with the Zeeman splitting. By giving explicit numbers we show that astable TS state is possible in both electron- and hole-doped semiconductors forexperimentally realistic values of parameters. We discuss possible suitablesemiconductor materials which should be the leading candidates for the Majoranasearch in solid state systems.
