In magnetotunneling I(V,B) measurements on strained p-type Si/Si1-xGex double-barrier resonant tunneling structures we observe heavy-hole satellite peaks that correspond to tunneling with Δn=1 and 2 changes in the Landau index n. The relative intensity of the satellite peaks excludes scattering as a possible mechanism. We ascribe the Δn=1,2 satellites to elastic tunneling made possible by Landau-level mixing in the valence band predicted by the Luttinger Hamiltonian in a magnetic field. The satellite peak spacing yields the valence-band Landau-level structure in strained Si1-xGex quantum wells. © 1993 The American Physical Society.
