We have achieved multiple-layer liquid epitaxial growth of Pb1−xSnx Te from Pb–Sn solution. Hall-effect and capacitance measurements determine carrier concentrations to be as low as 3 × 1015 cm−3 at 77 °K. Interference microscopy reveals that deviations from planarity of the grown surface are less than 1 μm over an area of 1 mm2.
