A planar interface was obtained in LPE grown Pb1−xSnxTe heterostructures using nominally oriented substrates by inducing a vertical thermal gradient normal to the substrate-solution interface at the moment of contact. It was found that this vertical gradient promoted very dense nucleation in heteroe...
