Abstract
We report the evolution of the first-order Raman modes of the layered semiconductor TlSbS2 with hydrostatic pressure applied up to 10 kbar. All the modes experience a blue shift, except the mode at 286 cm-1, whose insensitivity to pressure shows it to be governed by stretching of Sb-S diatomic chains in the layer. An axially symmetric short-range potential between nearest neighbors has been constructed to account for the full Raman spectrum. © 1989 The American Physical Society.
