Surface Phonons in Superlattices

B. Djafari-Rouhani, Leonard Dobrzynski, O. Hardouin Duparc

We report the existence of surface localized phonons for a superlattice consisting of alternating slabs (parallel to the surface) of two different crystals. The superlattice has a larger periodicity in the direction perpendicular to the slabs and therefore many phonon branches in the folded…

Transverse elastic waves in periodically layered infinite and semi-infinite media

R. Camley, B. Djafari-Rouhani, Leonard Dobrzynski, A. Maradudin

The propagation of transverse elastic waves both perpendicular and parallel to the laminations of infinite and semi-infinite periodically layered media is studied. The displacement fields and the dispersion relations for such waves are obtained analytically, and the latter are solved numerically to…

Sagittal elastic waves in infinite and semi-infinite superlattices

B. Djafari-Rouhani, Leonard Dobrzynski, O. Hardouin Duparc, R. Camley, A. Maradudin

Elastic waves, polarized in the sagittal plane, are investigated in infinite and semi-infinite superlattices made from alternate layers of two isotropic media. By the use of a transfer-matrix method, we obtain explicit equations for the dispersion of the bulk modes as well as of the surface modes…

Theoretical and experimental comparison between fundamental and harmonic operation of GaAs millimeter wave TEO's

Marie-Renée Friscourt, Paul-Alain Rolland, Georges Salmer, J. Lacombe

Simulations of GaAsmillimeter wave T.E.O.'s indicate the possibility of fundamental accumulation layer transit mode up to 100 GHz with higher conversion efficiency than that obtained with harmonic mode. Significant improvement in output power is expected from InP fundamental oscillators in the…
