  In this letter, we describe the stabilization of indium antimonide (InSb) in
the high-pressure orthorhombic phase (InSb-III) at ambient conditions. Until
now, InSb-III has only been observed above 9 GPa, or at around 3 GPa as a
metastable structure during the phase transition from cubic zinc blende
(InSb-I) to orthorhombic InSb-IV. The crystalline phase transition from InSb-I
to InSb-III was driven by an ultrashort, laser-generated, non-hydrostatic
pressure pulse. The transition occurred in preferred orientations locked to the
initial orientation of the InSb-I crystal, breaking the symmetry of the InSb-I
cubic cell to form the InSb-III orthorhombic cell.
