The energy subbands in pseudomorphic p-type Si/Si 1-x Ge x /Si quantum wells are calculated within the multiband effective-mass approximation that describes the heavy, light and split-off hole valence bands. We examine the intersubband transitions in this system and the selection rules are obtained
